Privacy and authorship note: this article is published by Smuvit at smuvit.com. The supplier-side commercial contact Luna Qian (lunaqiandudu@gmail.com) is named because she is the documented signatory of formal commercial correspondence on behalf of Jiangsu Weitian Yangchu Supply Chain Co., Ltd. (smoochine.com) and represented herself as such throughout the case. Personal data of the buyer-side staff has been redacted from screenshots and from the body of the article. For any inquiry related to this case, the corporate contact is hola@smuvit.com. No personal telephone numbers of any party are reproduced.
1. An open message to Jiangsu Weitian Yangchu Supply Chain Co., Ltd.
To the management of Jiangsu Weitian Yangchu Supply Chain Co., Ltd. — at No.9 Xinjiangping Road, Jingjiang Modern Agricultural Industrial Park, Taizhou City, Jiangsu, China — and to Luna Qian, as the sales counterpart on record:
This article is public, it is in six languages, and it has been written in a way that any search query for "Smoochine", "Smoochine 4.0", "Smoochine PM30CA1B", "Jiangsu Weitian Yangchu Supply Chain", "smoochine.com review", "smoochine.com complaint", "Taizhou Jiangsu smoothie machine supplier", or "Luna Qian Smoochine", performed by a future buyer in any of those markets, will find it.
It does not need to remain online. There is a clean, evidenced, and proportionate way to close this: refund the USD 5,000 paid under invoice CI-2025-0801, in line with the relief we already requested formally on March 4 and reiterated under CISG on March 11. On confirmation of the refund and the return of the unit, the article is taken down. This is not a threat — it is the same offer your company received in writing, in plain English, more than two months ago. The offer remains open.
In the meantime, this page exists as the public record. The choice of how long it remains the first thing a prospective Smoochine buyer reads is, and has always been, yours.
2. The numbers, plainly
What was paid, what was lost, and what was refused — in a single table that anyone reading this can verify against the PDFs further down:
- USD 5,000 — wire transfer paid to Jiangsu Weitian Yangchu Supply Chain Co., Ltd. on the order of August 1, 2025, invoice CI-2025-0801, for one Smoochine 4.0 PM30CA1B (serial P30200079).
- Return shipping of the first defective unit from Spain to China — paid by the buyer, by agreement with the supplier.
- ~€200 customs on the inbound replacement unit (serial P30200258, RMA-2025102001) — paid by the buyer, because the supplier-supplied customs paperwork was incorrect (the buyer raised this in writing on December 3, 2025).
- USD 61 (approx €55) FedEx delivery fee on the replacement motor that the supplier classified as a complimentary warranty part — paid by the buyer, at the supplier's explicit request: "would it be okay if you cover the delivery fee?" (Luna Qian, December 3, 2025).
- Additional local part sourced in Spain in February 2026 to keep the second unit running — paid by the buyer.
- Approx. 9 months of project paralysis, including postponed investor demonstrations, technical staff time spent on diagnostics rather than commercial operations, and reputational cost — entirely on the buyer.
- Refund of USD 5,000 requested formally on March 4, 2026 — refused in writing on March 9, 2026, by Jiangsu Weitian Yangchu Supply Chain Co., Ltd.
- Substantive reply to the buyer's CISG rebuttal of March 11, 2026 — not received, despite a 15-day deadline (expired March 26) and a follow-up of April 13, 2026 with a 7-day deadline (expired April 20).
3. Who is on each side of this case
The supplier — Jiangsu Weitian Yangchu Supply Chain Co., Ltd.
The seller of record is Jiangsu Weitian Yangchu Supply Chain Co., Ltd., operating the Smoochine brand through smoochine.com. The registered business address, as it appears on the supplier's own letterhead in the Official Response of March 9, 2026, is:
Jiangsu Weitian Yangchu Supply Chain Co., Ltd. — No.9 Xinjiangping Road, Jingjiang Modern Agricultural Industrial Park, Taizhou City, Jiangsu, China.
The product family is internally referenced as PM30CA1B (sprayed-finish) and PM30CA1Q (stainless-steel), and externally marketed as the Smoochine 4.0. The cloud back-end connects machines to the domain machine.m.vtian360.com; the internal management platform is known as VtianAdmin / TEAF5.
The sales counterpart throughout pre- and post-sale exchanges, signed in formal correspondence as a representative of the company, was Luna Qian (email lunaqiandudu@gmail.com; WhatsApp handle "LUNA JGROUP"). Their factory-side decisions in this case were, per Luna Qian's own messages, taken in coordination with their internal technical team and, ultimately, their management — who signed the refund refusal.
The buyer — Smuvit (Spain)
The buyer is Smuvit, a Spanish company building an automated smoothie business. The corporate contact for this case is hola@smuvit.com. We do not publish the personal identifiers (full names, phones, home addresses) of buyer-side staff in this article; nothing relevant to the case turns on those identifiers, and the supplier already has them in the case file.
4. What was promised — pre-purchase materials
Below are the official Smoochine price list and pre-sale demo videos that Jiangsu Weitian Yangchu Supply Chain Co., Ltd. sent during the pre-purchase conversation in June and July 2025. We reproduce them so that a future Smoochine buyer can match the same documents against their own quote:
4.1 What was claimed about the supplier's customers — including 7-Eleven, FamilyMart, Lawson and Haidilao
During the pre-purchase exchange we asked Luna Qian an explicit question about installed references. The exchange, as preserved verbatim in our WhatsApp record:
"European Case References — Are there installed cases in Europe (e.g., 7-Eleven, gyms, etc.) that we can visit or reference?"
"Equipment has been shipped to countries such as Spain, Poland, Finland, and Russia, but the specific store locations are not clear. There are numerous stores in China (including 7-Eleven, FamilyMart, Lawson, and Haidilao) available for visit."
In other words: when asked for a verifiable European reference list, the supplier could not produce one ("specific store locations are not clear"); in its place, the supplier offered the names of four globally-known retail chains — 7-Eleven, FamilyMart, Lawson, and Haidilao — as in-China references the buyer could "visit". We were never given any contract, invoice, purchase order, signed letter, framework agreement, or photograph in situ confirming that Jiangsu Weitian Yangchu Supply Chain Co., Ltd. or the Smoochine brand is, in fact, a supplier of any of those four chains.
The same kind of reference claim recurs in the supplier's Official Response of March 9, 2026, where Jiangsu Weitian Yangchu Supply Chain Co., Ltd. states verbatim: "Our machines are the first choice of many large chains worldwide and widely praised." Again, no supporting documentation has been provided to substantiate the assertion.
The 7-Eleven claim, checked against the public record
The reference to 7-Eleven is the most prominent of the four names invoked, so we checked it. Nikkei (Nihon Keizai Shimbun) — Japan's principal business daily — reports in writing that the in-store smoothie machine deployed by Seven-Eleven Japan is developed by Fuji Electric Co., Ltd. (Tokyo Stock Exchange ticker 6504), as part of Fuji Electric's broader equipment partnership with the convenience-store chain. Nikkei's wording, verbatim: 「セブン―イレブン・ジャパンと店内提供向けにスムージーマシンも開発しており」 ("[Fuji Electric] also develops smoothie machines together with Seven-Eleven Japan for in-store service"). An additional interview, published by Impress Watch's Gourmet Watch, describes the unit as 「何年も改良を重ねようやく完成した専用マシン」 ("a dedicated machine, completed after years of refinement") — i.e. a custom-built, exclusive piece of equipment, not a generic OEM product.
In other words: the in-store smoothie machine at 7-Eleven Japan is a dedicated unit developed by Fuji Electric (Japan). There is no public record — and the supplier in this case has not produced one privately either — connecting Jiangsu Weitian Yangchu Supply Chain Co., Ltd. or the Smoochine brand to the 7-Eleven in-store smoothie program in any market. The 7-Eleven reference offered to us during pre-purchase is therefore, on the verifiable public record, not accurate.
We have not separately verified the FamilyMart, Lawson and Haidilao references; the supplier never produced documentation for any of them either. We invite the procurement and corporate-communications teams of 7-Eleven Inc. (Seven & i Holdings), FamilyMart Co., Ltd., Lawson, Inc. and Haidilao International Holding Ltd. to publicly confirm or deny a current supplier relationship with Jiangsu Weitian Yangchu Supply Chain Co., Ltd. concerning the Smoochine 4.0 (PM30CA1B). We will update this article in full with their statement on receipt. The case-file contact is hola@smuvit.com.
Public sources used for this verification: Nikkei article «コンビニに富士電機あり 省エネ支援からスムージーまで» (Nikkei, 2022), Impress Watch Gourmet Watch interview on the Seven-Eleven Japan smoothie program, and the official Seven-Eleven Japan FAQ at faq.sej.co.jp.
5. The first unit — failures from day one (August–September 2025)
The first Smoochine 4.0 PM30CA1B unit (serial P30200079) arrived in Spain in August 2025. We powered it on, configured it strictly according to the supplier-provided manual, and ran acceptance tests. Within hours, we had four reproducible failures, all offline — i.e. not dependent on cloud connectivity, even though cloud connectivity was also broken:
- App connectivity: ~90% of the time the unit could not reach
machine.m.vtian360.com. Other devices on the same network reached the domain ~70% of the time, so the bulk of the failure was demonstrably not our network. - Door sensor: failed to register the door as closed in ~40% of attempts.
- "Start Making" button: unresponsive on ~80% of attempts.
- Water pump / level sensor: the machine would not draw water from the tank, and the sensor did not recognize that the tank was full.
We documented these failures on video, sent them to Luna Qian on WhatsApp, and shared them in the technical group set up by the supplier. Selected, representative clips below:
Presented with the evidence, Luna Qian offered two routes on behalf of the supplier: ship an engineer to Spain, or return the unit to China for factory inspection. We chose the return. We absorbed the cost of return shipping to China ourselves, by agreement with the supplier. We will return to this point: the buyer paid out-of-pocket to send the supplier's own defective unit back to the supplier's own factory.
The factory inspected the unit and reported back, in writing — language preserved verbatim in the Official Response of March 9, 2026:
"After receiving and testing the machine, we confirmed that there were no hardware or software defects at all. The issue was entirely caused by the local network environment. In fact, our manager encountered the same network problem in Indonesia recently, which can be easily solved by using a mobile hotspot." — Jiangsu Weitian Yangchu Supply Chain Co., Ltd., March 9, 2026.
The same letter that absolves the first machine of any defect also implies — by way of the Indonesia anecdote — that the supplier is aware of recurring connectivity issues with their own product in multiple markets, and proposes that the remedy is for the buyer to bypass the supplier's own cloud back-end via a mobile hotspot. We invite the reader to weigh this against the supplier's prior commercial statements about the product being "the first choice of many large chains worldwide".
6. The second unit — defective motor and a new buyer-side culprit (October–December 2025)
In October 2025, Jiangsu Weitian Yangchu Supply Chain Co., Ltd. shipped a replacement unit — serial P30200258, under reference RMA-2025102001. From the very first stress tests, a new pattern of mechanical failures appeared.
6.1 Rail vibration and noise
The internal rail system produced loud, rhythmic vibration when sliding the cup in and out. Documented on November 27, 2025 and again on December 19, 2025:
6.2 Top-motor vibration and visible shaft misalignment
Stress testing revealed a more serious defect: the screws holding the top motor were found loose during normal operation. Tightening them reduced the noise but did not eliminate it; the shaft showed visible oscillation, propagating vibration through the entire chassis. During testing the vibration was strong enough to break a cup.
Our message to Luna Qian on November 27 explicitly described the defect we suspected — "the screws holding the upper motor were loose. After tightening them, the noise was reduced — but the machine still vibrates significantly. We also observed that the shaft seems to be slightly bent or misaligned, causing it to oscillate strongly when spinning."
6.3 The pivot — from "we don't know" to "the buyer's fruit"
Luna Qian's first reaction, on behalf of the supplier's technical team, was the following sequence — reproduced verbatim from WhatsApp on November 27, 2025:
"Dear [Buyer], I have just confirmed with our technical team and would like to update you on this matter. We are writing to confirm whether you are using double-frozen fruit in the cups for mixing. This is because the spare parts of the current machine are slightly different from those of the previously delivered units."
"What do you mean with twice-frozen fruit? 😅"
"When fruit ice cubes melt and then refreeze, they become extremely hard. Could you please confirm if you are using such hard fruit?"
"Oh no, just frozen one time." — followed by photographs of the fruit:
The "twice-frozen fruit" theory did not survive the buyer's answer. Luna Qian's internal position, the following day, on November 28, 2025, was actually this — also from WhatsApp:
"Sorry for the late reply. I just checked with my colleague — we're confused as to why this issue occurred. To resolve it, please follow these two steps: 1. First, you'll need to replace the motor; 2. Second, please cut the frozen fruit into 2cm x 2cm cubes before using the machine."
"We're confused as to why this issue occurred" is the same supplier — the same Luna Qian — and the same Jiangsu Weitian Yangchu Supply Chain Co., Ltd. that, three months later, on March 9, 2026, would write that the motor failure was caused by the buyer using "frozen cups" and providing "insufficient water inside the cup". The two positions cannot both be true. The buyer kept the receipts.
6.4 The "complimentary" motor that the buyer paid to ship
The supplier proposed sending a replacement motor under the 12-month warranty. On December 3, 2025, on WhatsApp, the request came back in Luna Qian's own words:
"They've kindly agreed to let me use this method to address the problem. Good news is, we can offer this spare part complimentary for you; though just a small note — would it be okay if you cover the delivery fee?"
The delivery fee turned out to be USD 61 (approx €55). The buyer paid it. The replacement motor cleared Spanish customs on December 23, 2025. After installation, the unit's mechanical issues persisted; in February 2026 the buyer had to source another local part out-of-pocket to keep the machine running. Each of these incidents is logged in the supplier-administered WeChat technical group.
7. The formal demand, the formal refusal, and 60+ days of silence (March–May 2026)
7.1 March 4, 2026 — Formal Notice of Warranty Breach and Demand for Refund
On March 4, 2026, the Smuvit compliance team sent — by email to Luna Qian's lunaqiandudu@gmail.com — the formal notice of warranty breach and demand for refund. The operative paragraph of the attached PDF stated that the machine:
"fails to operate reliably, presents structural and mechanical defects, does not perform adequate blending for commercial use, requires continuous remote configuration intervention, and has not provided a stable, functional MVP after more than seven (7) months."
The relief sought: a refund of USD 5,000. As a goodwill concession, Smuvit offered to absorb the return shipping cost and to waive any claim for the additional costs already incurred (customs duties, logistics, locally-sourced parts, and technical labour).
The cover email is reproduced in part:
"Dear Luna,
Please find attached a formal notice regarding the Smoochine 4.0 machine supplied under warranty replacement. Our objective remains to resolve this matter professionally and amicably.
As explained in the attached document, we are requesting a refund of the USD 5,000 purchase price. As a gesture of goodwill and in order to facilitate a smooth resolution, we are willing to assume the return shipping cost of the machine and we are not seeking reimbursement of the additional costs we have already absorbed, including replacement logistics and local technical expenses.
We believe this is a balanced and reasonable solution considering the circumstances. […]"
7.2 March 9, 2026 — Supplier's Official Response: refund refused
Five days later, Luna Qian forwarded the company's official response, signed by Jiangsu Weitian Yangchu Supply Chain Co., Ltd. The reply was unequivocal:
"Dear [Buyer],
Here is our company's official reply. From my perspective, we have already communicated with each other for around six months, and we both paid a lot of attention to this project. I'm really sad that we have to send this kind of email to discuss these issues, but I hope we can still solve these problems properly.
Hope you enjoy your day."
The attached company letter — on company letterhead, with the registered Taizhou address — said, in its operative paragraphs:
"You chose the second option. After receiving and testing the machine, we confirmed that there were no hardware or software defects at all. The issue was entirely caused by the local network environment. In fact, our manager encountered the same network problem in Indonesia recently, which can be easily solved by using a mobile hotspot." — Jiangsu Weitian Yangchu Supply Chain Co., Ltd., March 9, 2026.
"Later you informed us that the motor of the machine was faulty. Based on our experience, such issues are usually caused by using repeatedly frozen cups or insufficient water inside the cup." — same letter.
"Unfortunately, you rejected all solutions and insisted on a full refund. […] If you give up halfway and lose confidence in the machine due to improper use, you will not only miss an excellent business opportunity in the smoothie machine market but also, we believe, miss other business opportunities as well. After careful consideration, we are unable to approve the refund, but we will honor our 1-year warranty and fulfill our repair obligations." — same letter, final paragraphs.
We invite the reader to re-read the second-to-last sentence above. A refund-refusal letter that, in the same paragraph, suggests the buyer will "miss other business opportunities as well" is the supplier's chosen tone of business correspondence — not ours.
7.3 March 11, 2026 — Smuvit's formal rebuttal under CISG
Two days later, Smuvit replied with a point-by-point formal rebuttal, citing the United Nations Convention on Contracts for the International Sale of Goods (CISG), invoked specifically as binding international law on both parties:
"Dear Luna, dear management team of Jiangsu Weitian Yangchu Supply Chain Co., Ltd.,
We acknowledge receipt of your official response dated 9 March 2026.
Please find attached our formal rebuttal document, which addresses each of the claims set out in your response on a point-by-point basis, supported by documentary evidence drawn from our WhatsApp and WeChat records […]
Your response does not engage with the substance of the defects documented over the past seven months, nor with the evidence submitted throughout this period. The attached document sets out why each of your assertions is factually inaccurate and legally unsustainable.
Pursuant to Article 49(1)(a) of the United Nations Convention on Contracts for the International Sale of Goods (CISG), and on the grounds of fundamental breach of contract within the meaning of Article 25 CISG, we hereby formally declare this contract avoided and demand restitution of USD 5,000 in accordance with Article 81(2) CISG.
We request your written confirmation of acceptance within fifteen (15) calendar days of the date of this communication. Should we not receive a substantive response within this period, we will exercise all rights and remedies available to us under applicable law. […]"
The 15-day deadline expired on March 26, 2026. No substantive reply was received.
7.4 April 13, 2026 — Smuvit's follow-up
One month later, Smuvit followed up:
"Dear Luna, dear management team,
We refer to our formal rebuttal sent on 11 March 2026, in which we addressed your previous response in detail and formally declared the contract avoided under the CISG, requesting restitution of USD 5,000.
More than thirty (30) days have now passed, and we have not received any substantive reply addressing the arguments and evidence provided.
Given the extensive documentation already shared — including repeated hardware failures in both units, unsuccessful repair attempts over a seven-month period, and acknowledgments from your own technical team — the absence of any response is a matter of concern. […]
This email is sent as a formal follow-up for the record. We remain available to resolve this matter amicably and kindly request your substantive response within seven (7) calendar days from receipt of this email. […]"
The 7-day deadline expired on April 20, 2026. As of the publication of this article on May 12, 2026 — more than 60 days after the CISG rebuttal — the supplier has issued no substantive reply to either communication.
7.5 The pattern, made explicit
Plotted as a single timeline, what Jiangsu Weitian Yangchu Supply Chain Co., Ltd. has done in this case looks like this:
8. Who paid for what — the asymmetry, on a single page
One of the more remarkable features of this case is that every shipping and customs cost generated by the supplier's defects has been paid by the buyer:
- The factory paid: nothing beyond a 12-month warranty letter and one replacement motor.
- The buyer paid: USD 5,000 (purchase) + return shipping of the defective unit to China + ~€200 Spanish customs on the inbound replacement + USD 61 FedEx for the "complimentary" warranty motor + an additional local part in February 2026 + ~9 months of project paralysis + the staff time of three rounds of formal legal correspondence.
In a properly-conducted international warranty dispute under the CISG (Articles 35, 45, 46, 74, 81), shipping costs of returning non-conforming goods are the seller's, not the buyer's. The buyer agreed to absorb them only in pursuit of a fast amicable resolution. The pattern that has emerged instead is that the more goodwill the buyer extends, the more the supplier accepts it as the buyer's permanent share of the burden. We are publishing this so that any future Smoochine buyer reads it before agreeing to a similar concession.
9. The supplier's corporate footprint — JGroup Beverage, TEAF5, Pumen Electronics, Shangjie Beverage
For any prospective buyer doing due diligence on this product, this section consolidates the publicly verifiable identity of the corporate group behind the Smoochine brand and the PM30CA1B (also referenced internally as PM30CA1Q for the stainless-steel variant). All facts in this section are anchored to public sources cited inline; any link between specific legal entities that is not publicly documented is signalled as such.
9.1 The group: JGroup Beverage (Shanghai) Co., Ltd.
The Smoochine brand and the TEAF5 product line are operated by JGroup Beverage (Shanghai) Co., Ltd. (捷翔饮品（上海）有限公司). Per the company's own corporate page (jgroup360.com) and the public Crunchbase profile of its founder:
- Founded: 4 May 2012.
- Headquarters: Minhang District, Shanghai, China.
- Founder & CEO: Wang Genzu (Genzu Wang, 王根祖; also referenced in some sources as Thomas Wang). Graduate of Nanjing Agricultural University (agricultural engineering). Crunchbase profile: crunchbase.com/person/genzu-wang.
- Reported 2023 group revenue: ~200 million yuan, with declared customers among China's leading tea-chain, new-retail-chain and bottled-beverage segments.
- Corporate websites: teaf5.com and the mirror jgroup360.com; consumer/Shopify brand site smoochine.com; back-end administration domain
vtian360.com(referenced earlier asmachine.m.vtian360.comfor connected machines).
9.2 The two wholly-owned manufacturing entities in Taizhou, Jiangsu
JGroup's own corporate description states that the group operates two wholly-owned factories in the Taizhou Pharmaceutical (Medical) High-Tech Zone, Jiangsu Province. Publicly identified as:
- Jiangsu Pumen Electronics Co., Ltd. (江苏普门电子有限公司) — the manufacturer of the smoothie machines. PUMEN Electronic publicly claims patents, sales to 30+ countries and 30,000+ units shipped. This is the entity most plausibly behind the physical assembly of the PM30CA1B / PM30CA1Q.
- Jiangsu Shangjie Beverage Technology Co., Ltd. (江苏上捷饮品科技有限公司) — the beverage/raw-materials arm of the group.
9.3 The entity that signed the refund refusal in this case
The Official Response of 9 March 2026 refusing this buyer's refund (see section 7.2 above) is signed by Jiangsu Weitian Yangchu Supply Chain Co., Ltd. (江苏唯甜养厨供应链有限公司), registered at No.9 Xinjiangping Road, Jingjiang Modern Agricultural Industrial Park, Taizhou City, Jiangsu, China. The Smoochine commercial sales counterpart on this case, Luna Qian (lunaqiandudu@gmail.com), explicitly identified herself as a representative of that entity in formal correspondence.
The corporate relationship between Jiangsu Weitian Yangchu Supply Chain Co., Ltd. and JGroup Beverage (Shanghai) Co., Ltd. — common ownership, subsidiary, sales/export arm, distribution licensee or otherwise — is not documented in the public sources we have consulted as of the publication date. Both entities operate around the same physical industrial cluster (Taizhou, Jiangsu) and serve the same product line (Smoochine / TEAF5 / PM30CA1B). We invite any reader with verifiable public documentation on that relationship to write to hola@smuvit.com; we will update this section accordingly.
10. Where the Smoochine PM30CA1B and the wider TEAF5 / JGroup catalog are distributed internationally — documented channels
The same product family (Smoochine 4.0 / PM30CA1B / PM30CA1Q / "Cell Wall Breaking Blender" / "Fully Automatic Smoothie Vending Machine") is listed for sale through several documented channels. We publish this list so that any future buyer can recognise the same machine across price points and trading platforms — including buyers whose first contact with the product happens not through smoochine.com but through Alibaba, AliExpress, the manufacturer's own catalog on teaf5.com / jgroup360.com, or a local distributor.
10.1 The wider group catalog — teaf5.com and jgroup360.com
The manufacturer's own sites (teaf5.com and the mirror jgroup360.com) host the full product catalog of the group. The catalog includes, at minimum, the following SKUs visible at the date of publication:
| Model | Product | Manufacturer page | Notes |
|---|---|---|---|
| PM30CA1B | Smoochine 4.0 — 4th-generation high-speed smoothie machine (sprayed finish) | teaf5.com/pd.jsp?id=23 | The unit referenced throughout this case. 22,000 rpm motor, 1,600 W blending + 2,200 W heating, 21.5" touch screen, R290 refrigerant. |
| PM30CA1Q | Smoochine 4.0 — full stainless-steel variant of the 4th-generation | teaf5.com/pd.jsp?id=25 | Same platform in stainless finish; cold + hot beverage capable, 22,000 rpm. |
| PM30CA1A | Smoochine 3.0 — previous-generation low-speed model | teaf5.com/pd.jsp?id=24 | 8,000 rpm motor, 1,600 W, 320×450×720 mm, automatic pipeline cleaning and hot-water sanitisation. |
| Ready Blending Cup | Pre-filled frozen-fruit "ice cup" line | teaf5.com/pd.jsp?id=22 | Consumable side of the Smoochine ecosystem (e.g. "Creamy Corn and Milk Smoothie Cup 奶香玉米奶露"). |
The mirror domain jgroup360.com/col.jsp?id=104 hosts the same product index under the same CMS. For any prospective buyer doing due diligence on the supplier, both domains should be treated as the same catalog, operated by the same corporate group (JGroup Beverage Shanghai), and used interchangeably for Chinese-domestic and international buyer flows.
10.2 Third-party channels reselling the same product family
| Channel | Region | URL | Notes |
|---|---|---|---|
| Smoochine official store (Shopify) | International | smoochine.com | Public list price USD 5,800 (12 May 2026). |
| TEAF5 / JGroup corporate | China + international | teaf5.com/pd.jsp?id=23 | Manufacturer product page. |
| JGroup360 mirror | China | jgroup360.com/col.jsp?id=110 | Mirror of the manufacturer catalog under the same CMS. |
| Alibaba.com (EN) | B2B international | alibaba.com listing | Direct order possible for B2B buyers. |
| Alibaba.com (ES) | B2B Europe / LatAm | spanish.alibaba.com listing | Same machine listed in Spanish for Hispanic markets. |
| AliExpress | B2C international | aliexpress.com listing | Same product, PM30CA1B model. |
| Vending Smart Australia | Australia | vendingsmart.com.au | Distributor explicitly listing model "PM30CA1B"; advertises a "2-Year Replacement Warranty" (year 1 brand-new, year 2 refurbished). Contact: hello@VendingSmart.com.au. |
All external links in the table above are marked rel="nofollow noopener". The list is provided for traceability of the product family across channels; inclusion does not imply that any of the listed distributors share or endorse the buyer-side position described in this article.
11. Why this is public — and what would close it
This article exists for three audiences. Each gets the same facts.
- To anyone considering a purchase from Jiangsu Weitian Yangchu Supply Chain Co., Ltd. (smoochine.com). Read everything above. Then negotiate as if you had read it before paying — not after. The single most consequential decision you will make is the payment method: a credit card preserves chargeback; a T/T bank wire does not.
- To the management of Jiangsu Weitian Yangchu Supply Chain Co., Ltd. The position remains exactly as stated on March 4 and reiterated on March 11 under CISG: refund USD 5,000, confirm return-shipping instructions, and this case closes. The article will be taken down. No claim will be made on the additional costs the buyer has already absorbed. The path back to a normal commercial relationship — which Smuvit explicitly left open in writing — is still open.
- To Luna Qian personally, as the documented commercial counterpart. Your own messages, quoted at length above, are in the record. You wrote on March 9, 2026: "I hope we can still solve these problems properly." So do we. The clean resolution remains the same one Smuvit has been asking for for two months.
12. What we would tell a future buyer of any Chinese factory equipment
- Pay by credit card. Not by T/T bank transfer. A credit card gives you 60–120 days of chargeback protection. A T/T to a Chinese factory gives you a polite WhatsApp thread.
- Insist on a written international arbitration clause (CIETAC, HKIAC, SIAC) and a governing-law clause before payment. If you don't have one in the order, you don't have leverage; you have a hope.
- Demand a Factory Acceptance Test under conditions equivalent to your real market. Your network, your fruit, your cups, your electricity. Signed FAT report before shipping.
- Document every communication from day one, with backups. Email beats WhatsApp; WhatsApp with cloud backup beats WhatsApp without. Every voice note transcribed, every photo timestamped.
- Assume the post-sale narrative will be that the defect is your fault. Design your evidence pipeline for that scenario before the first failure, not after.
- Never absorb a shipping or customs cost that is contractually the seller's. Once you do, you set a precedent the seller will rely on for everything that comes next.
13. A note on tone and on why this article reads the way it reads
We have made specific editorial choices. We have quoted Jiangsu Weitian Yangchu Supply Chain Co., Ltd. verbatim from formal correspondence and from WhatsApp, with timestamps. We have linked the underlying PDFs in full, so any reader can verify what we have written against the source documents. We have not used generic accusatory labels such as "fraud" or "scam" against the supplier; we have described — strictly — what was paid, what was received, what broke, what was claimed, and what was refused. Where this article reads as firm, it is because the underlying facts read as firm.
This article does not constitute a general assessment of the quality of all products of the Smoochine brand or of Jiangsu Weitian Yangchu Supply Chain Co., Ltd. It is a narrow, evidenced account of this specific case, published for the benefit of every search query that arrives at this page before — not after — a payment, and as a public record of a dispute that, as of publication, the supplier has chosen to leave unanswered.
