Additionally, some customers expressed frustration over unexpected shipping costs and complications during the checkout process.
Unbelievably dishonest company and support. Purchased a MR60BHA2 which was advertised as being used by someone on a couch and someone at a desk. The sensor is horribly inaccurate, saying I'm breathing 20 breaths per minute when holding my breath, showing my heartrate at 110bpm when Apple Watch shows 65bpm. Support refused to accept a return/refund, or even a replacement, stating that it is only to be used on a bed (???) and editing their wiki after sending the reply, to remove the desk example. So dishonest, yet another scamming company. If things change, I will update this review accordingly.

We’re sorry to hear about your experience and appreciate you sharing your feedback.
The MR60BHA2 is a non-contact radar developer kit intended for research and system integration purposes. It is not a medical-grade device, and its heart rate and breathing outputs are based on radar micro-motion signal estimation rather than direct physiological measurement. As a result, readings may differ from wearable devices such as an Apple Watch.
For heart and breathing monitoring, the module is designed primarily for static, single-person use in sleep scenarios, and performance is highly dependent on installation and environmental conditions. We continuously work to improve documentation and clarify usage guidelines to avoid misunderstandings.

The most buggy website I have ever used.
Full of bugs in the ordering part, allocated money on my account multiple times, no order actually went through.
Ran into two visual errors when buying. Attempted using Mastercard and paypal. Mastercard woudn't work, paypal did but still did not go through, even if there was no errors.
I do NOT recommend. I have contacted them and informed them about the errors on the website.

They sent the wrong product. Left with no response after asking to resolve the issue.
I purchased a SeeedStudio synth module, but received a camera module instead. I asked a refund or exchange after receiving the wrong product from SeedStudio. Customer support is ghosting all channels, email, chat support,... name it. After 10 days of trying, I get no response on how I can exchange the wrong item for the right one.
I ordered all my items from the German EU shop, hoping this would give me the least trouble, but turns out to be wishful thinking.
Seeed Studio 回复2026-04-03
Thank you for your feedback, and we sincerely apologize for this poor experience.
You chose our German EU store expecting a smoother process, but instead received the wrong item and couldn't reach customer service for 10 days—this falls short of our standards, and we understand your frustration.
Sending the wrong product was our mistake, and failing to respond was our responsibility. Here's how we'll resolve it: we'll send you the correct synthesizer module at no cost, and you may keep the camera module—no need to return it.
Regarding the unreachable service, we've escalated your case. We couldn't locate the emails you sent, so please forward your order number to
[email protected], and we'll follow up to ensure resolution.
We apologize again. We'll take immediate steps to improve, and look forward to making things right.
Delivery was ok and fast but ... product did not perform as expected, so I asked for a refund. Not possible, simply because the item had already been used, as stated by Customer Service.
In the early days of web shopping this was a common 'web shop attitude' but later forbidden by EU law. A customer has the right to test the item and return it in case it does not perform or does not meet expectations (with the item in original state and packaging). After all, such a device can be reset and is not a consumable.
Seeed Studio 回复2026-04-03
Thank you for your feedback. We regret that the product did not perform as you expected.
Regarding your refund request, we would like to clarify that if the product does not have a quality defect and has already been used, we generally do not accept returns. This is to ensure that other customers receive products that are brand new and unused. We hope for your understanding.
As for the EU law you mentioned, we will take note of it and escalate your case to the relevant team for further review, so that we can continue to improve our after-sales policy in the future.
Thank you for bringing this to our attention.
WoW, wish I had read the reviews prior to ordering from these clowns. Ordered RPI CM4 a week ago have asked for order/shipping status 3 times and no response even though it's supposed to ship from US warehouse and to me in US. Last and only time I purchase anything from them.

We apologize again for this unpleasant experience, and thank you for giving us the opportunity to investigate the matter.
I purchased a reSpeaker AI Kit on Saturday and cancelled it a few minutes later. The purpose of the cancellation was to purchase with expedited shipping. Instead today I get an e-mail today that they cannot cancel my order and that I will be charged 13% to return the product. I find it very disheartening to be treated in this way as a customer. I would warn anyone against purchasing from this vendor as they have very unsavory tactics to sell their products.

Thank you for your feedback. We sincerely apologize for your poor return experience.
At the time, your order had already been uploaded to our overseas warehouse's packing system and could not be automatically canceled, so the package was ultimately shipped. Please note that the overseas warehouse is a third-party facility we lease, which does not accept return processing. As a result, the product had to be returned to China. This situation arose due to deficiencies in our return policy at the time — you should not have borne any of the associated costs.
Since last October, we have fully improved our policy: for any returns resulting from system failures to cancel orders, we will bear all related costs — customers will not be exposed to any risk. In addition, orders valued under 500 USD can now be returned to our overseas warehouse.
We regret that we did not see your message sooner. If you have incurred any losses as a result of this order, please contact us at [email protected], and we will provide appropriate compensation.
Once again, we sincerely apologize for the inconvenience caused.
Seeed Studio offer's pretty cool hardware for your smart home. I ordered a set of epaper display, epaper driver board and fitting ESP32-C3 from them. epapers shipped from China, the rest from Germany. After fiddling around with it, I had to find out, that I either had defect epaper, or ESP32 and driver board. From their perspective it's the cheapest, hence ESP32 and driver board, which they wanted to send me.
After 3 weeks of waiting, I started issuing a paypal claim and out of the sudden the replacement hardware is shipping.
Still my epaper display's are the problem, as also with the original ESP32 driver board from Waveshare these displays are not getting to work.
Don't waste your money on them, if you're unsure to receive working parts. Btw. if you read their site thoroughly, all parts must be returned to china on own cost!!!

Thank you for your feedback. We sincerely apologize for the trouble and frustration you experienced during the hardware debugging process.
Regarding the compatibility issues and the delayed shipment of replacement parts, we have strengthened our pre-shipment quality control. In addition, our after-sales policy has been improved: if a product is confirmed to have a quality defect, we will cover all related costs, including return and exchange shipping fees.
Please send your order information to [email protected]. We will reassess the situation and handle it properly.
We apologize once again and thank you for your valuable feedback.
These guys are lying thieves; I've ordered a home assistant yeloow, and cancelled the day after in the morning. (website stated i could cancel as long the order was in processing).. An hour later i received a mail, instead of my cancellation it stated that the order was shipped. After contacting them and explaining there was something wrong; They just said, i should keep it or send it back to china with a 13% surcharce tax and shipping fee..(it shipped from germany by the way) Or i should refuse the shippment, that would mean stay at home from work to refuse the package. Never in my life have I experience such unproffesional behaviour with an onlne shop .. If you are in europe or usa DO NOT ORDER from these guys

Thank you for your feedback, and we sincerely apologize for this terrible return experience.
At the time, your order had already been uploaded to our German warehouse's packing system and could not be automatically canceled, so it was still shipped. The German warehouse is a leased facility that does not accept returns, so the item had to be returned to China. This was due to our previous inadequate return policy, and you should not have had to bear the cost.
Since October last year, we have improved our policy: for returns caused by system failures to cancel orders, we now cover all related costs—customers do not need to take any risk.
We are sorry we did not see your comment earlier. If you incurred any loss from this order, please contact us at [email protected], and we will compensate you.
Extremely opaque return policy, international returns make refunds unreasonable
I ordered a product worth €70, but canceled the order before it was shipped. Despite this, the item was still sent out.
When I requested a return, I was told:
I have to return the item at my OWN expense to CHINA, even though it was shipped from a GERMAN warehouse (This is not stated anywhere on their website).
The return must include a tracking number, increasing the cost to at least €30.
They told me to declare a very low value (5 USD) to avoid Chinese customs fees which they would deduct from my refund.
After all deductions, I would only be refunded $54.78 (about €48), meaning over 30% of the original price is lost, even though the item is unused and unopened.
Nowhere during the purchase process was it made clear that returns must be shipped to China at the buyer’s cost. This lack of transparency is unacceptable. The return conditions are buried in email threads after purchase, not visible before buying.
Summary:
Order shipped from Germany
Return only possible to China
Customer pays for all return shipping and risk
Refund heavily reduced by unclear extra charges
I do not recommend buying from Seeed if you expect any kind of fair or manageable return policy. Once you’ve placed an order, you’re basically stuck with it—even if you cancel it right away.

Not sure what has happened to this company but I would avoid.

Thank you for your feedback. We apologize for the frustration this has caused.
We understand your concerns regarding order cancellation and fulfillment. To clarify: orders are processed quickly and enter automated fulfillment, with estimated delivery times clearly indicated during checkout. Customers can cancel an order and request a refund before the status changes to "Processing." Once an order enters processing, cancellation options become limited.

We are also improving how our cancellation and refund policies are communicated to ensure greater clarity going forward. Thank you for bringing this to our attention.
placed order, per website order would be shipped within a few days. a week went by still processing. I contacted seeed, it took them 3 days to respond, they lied and provided a tracking number that didnt work and said it had already shipped. Then no updates no communication. my order page still said processing so i reached out again and they said the package was lost and no inventory for 2 months. they only said something after me reaching out. Terrible communication and dishonesty. I dont think anything was ever sent. avoid this company.

We are reviewing our fulfillment and communication processes to prevent issues like this from happening again. Thank you for giving us the opportunity to improve. Have a good day.
Nothing is special about this product and I question its legitimacy.. Once you order you better watch that account, they start doing re-occurring charges and not sending any product... ITS A SCAM out of southern California of all places.

Extremely Frustrating and Inefficient After-Sales Process
I am deeply disappointed with Seeed Studio's after-sales service. I purchased their HA ZBT-1 device in September, which turned out to be defective. While I appreciated their announcement of a replacement program, the actual process has been nothing short of a nightmare.
After following all their instructions—submitting a ticket, providing the order number, and sending photos of the defective product—I was repeatedly asked to fill out the ticket again and again. Despite weeks of back-and-forth emails, they claim they cannot locate my information even though I’ve provided everything multiple times.
What’s most frustrating is that the responses from their support team feel robotic and lack accountability. There’s no sense of urgency or ownership, and I keep getting the runaround with no resolution in sight.
At this point, it feels like they are intentionally avoiding replacing the defective product.
I would strongly caution anyone considering a purchase from this company to be aware of their poor customer service and unreliable after-sales support.
Web site is ok and shipping was fairly prompt. But you better hope that whatever hardware you receive isn't defective. Their support will make you jump through hoops blaming your setup and/or the software. I complied with their requests and submitted fairly conclusive proof that the hardware board was defective. It became clear that they were not going to replace the hardware no matter what I submitted as proof. This was a $20 product and not worth hours of my time. So, they win. I tossed the board in the trash and moved on. Will never order from them again.
I purchased a water block for a raspberry pi 5. It was and still is advertised as having G1/4 threaded ports. As I have been water cooling for nearly 25 years, I have a lot of excess parts and was interested in watercooling a cluster of pi's. I purchased 2 of these blocks and gathered the rest of the parts for the system. Once received, I removed the original barbs and immediately noticed they were not G1/4. They were actually G1/8. I sent an email to support with a picture of the G1/4 fitting I owned next to the original fitting supplied. They replied that the ports should be a standard G1/4 (which is why i purchased them) and referred me to the installation wiki and if I had further issues to send pictures. I don't need a wiki to screw in a fitting that is too large for the thread its intended for. Also asked me to send pics if I had further issues, which I had already done with my initial support request. Postage was extremely fast. China to Australia in 1 business day. But their lack of support and clear error in advertising is disappointing.
Are you interested in exploring the world of microprocessors and BLE communications? Well the Seeed Studios XIAO nRF52840 is not the way to go. Like many other Chinese manufactures, the electronics are sound and have great results in past however, their failure to keep the hardware drivers and software libraries up to date have rendered the product useless for the beginner. Trying to use the product today in the Arduino IDE is nothing short of heart wrenching frustration as the simplest program won't compile due to out of date libraries. Save your money. Use a non Seeed Studio device.
Purchased a "plug and play" mmwave presence sensor. Followed instruction on their website couldn't get it to work. Asked tech support via email how to get it working, provided logs, detailed description of problem and screen shots. Week later got response on how it is supposed to work not how to fix it. Resent email a week ago no response. If you read prior complaints you will see a trend. They have no intention of supporting their product or worse don't know how. If you purchase from them don't complain if you don't get support. Enough people here have warned you
They sold me a "plug and play" device. They would not allow returns or refunds, once you get it you quickly learn its not even close to a plug and play device! Thier support is by far the worst I've ever tried to deal with I now have a $400 paperweight because I'm not a computer programmer. They are a rip off stay as far away from them as you can! SCAMMERS
We bought Home Assistant yellow kit, Raspberry pi CM4 and NVMEe SSD for 249$ without shipping but they send us Home Assistant yellow kit only, when we contact them on email they replied for a few time then they completely ignored us,
