I purchased my first hyperbaric oxygen chamber from these guys a few months ago. I had no idea whether I would even enjoy the sessions, so it felt like a bit of a leap! The good news is, I have been pleasantly surprised.
The chamber and accessories were packed very well and arrived safely in my country hometown in South Australia. The quality is excellent, and the machine has functioned perfectly over the past couple of months. I have contacted Cindy at Tecnotu a number of times, and she has been helpful and efficient every time. Thank you, Cindy!
Since starting my sessions, I’ve noticed some easing of the pain in my leg, along with a positive shift in my energy and mood. I’m really pleased with my experience so far.
Thank you to everyone at Tecnotu. Based on my experience, I would happily recommend them to anyone considering purchasing a chamber.

Great Product - Great Customer Service
I purchased the softshell laydown 1.5ATA chamber from Cindy. I am absolutely thrilled with the chamber. I am using it daily, and have had only a couple issues that were addressed quickly. To me, the system is worth every penny that I paid for it. It's going to pay for itself within a couple months. If anything goes sideways, I'll be back to update. At this point, I am extremely happy with my purchase.

Great Product & Experience
I have been very pleased with the product and company. I had a great experience.
With being from PA, I was nervous to purchase a product from out of country, but they were patient with me, were workable, and answered all of my questions.
The valve was faulty, but they took care of the problem asap and shipped a replacement along with a few extras. I was pleased with how they handled the issue.
They were great to work with, and I recommend going with Tecnotu. I am glad I did.

I Bought the soft cover 1,5ATM and at…
I Bought the soft cover 1,5ATA and at first I liked how everything looked online and the customer service expressed not to worry. The unit arrived and the oxygen concentrator was not working. I provided pictures to them and requested a return as they offer a return policy. They responded explaining that a cable might had disconnected it. They first suggested to try to connect the cable and then they offered a full replacement. I was able to connect the cable but the oxygen had a error when it started. The customer service replied messages when I questioned the oxygen concentrator. When I was trying to assemble the chamber I had a question about the fittings and customer service answered those questions about the fittings to assemble the chamber. They have a video online to build the unit. As I was getting a shipping I decided to order the bracket so the unit will stand on its own.
8/28/25 UPDATE: The shipping with the bracket and oxygen concentrator arrived. We assembled the bracket as all the pieces worked as intended, it was like a simple puzzle with about 8 metal pieces, some screws and four straps. Once the bracket structure was assembled it we tied the chamber to the bracket and we were very happy with the upgrade as it is more functional when entering, starting the unit and leaving. I have not fully tested yet and I will come back to update the full experience with TECNOTU as I get to test the actual chamber. So far glad with the price, the fact it arrived, I was frustrated with the oxygen concentrator and the additional work it took but the fact they replied, replaced the oxygen concentrator and provided help through the process helped a lot. In my experience it gave me confidence when there was a problem and they offered help to solve it. I would buy from them again.

Warning to those thinking of buying from TECNOTU.
At the end of Dec 2024 I ordered a 1.5 soft-shell hyperbaric chamber from Tecnotu through ebay. On receipt of the chamber in late Jan I found the plug was broken and upon getting this fixed - nothing worked anyway. I told the company I wanted to return. They assured me the chamber must have a leak and that if they sent me a new chamber everything would be okay. Because of businesses and factories being closed for Chinese New Year I had to wait 7 weeks to receive the new chamber. By this time my refund guarantee with ebay (30 days) had elapsed. The new chamber didnt work. I then waited for 3 more weeks for new pressure relief valves (as Tecnotu were now saying this must be the issue). When they arrived it still didnt work. It is now May 2025 and in total I have spent £3500 on this product and it has NEVER WORKED. I have repeatedly asked for a refund and Tecnotu knows it has NEVER ONCE WORKED, as I have recorded everything with someone called Cindy (absolutely clueless about chambers) on WhatsApp for the past 5 months. They will not issue one and have now stopped responding to me. I've also had an expert in my country (the U.K) inform me that the product should not have crossed the border into this country as it has not been adequately safety-tested and has no data or stamp on it that confirms any of this testing. I have made a complaint to both ebay and my bank and my bank is currently investigating this company. I'm also planning to report this company to the Office for Product Safety and Standards in the UK, who, once they are aware of the compliance issues with Tecnotu's products, may well ban their sale in the UK (to be specific about one key test these chambers would need in the UK that this company does not have a certificate for - PVHO testing. These tests ensure the safety and reliability of the structure under the immense pressure in undergoes upon inflation. Without these guarantees a person can experience serious injury or death if a chamber filled with oxygen - which is highly reactive - bursts). I am currently in conversation with the UK International Consumer Centre and I have also written to the trade division of the Chinese Embassy to make a complaint about this company. I bought this chamber because I have a long-standing health issue (which I made clear to the company) and because it looked like a good deal cost-wise to do so, but if you are considering doing the same thing - perhaps because you are also treating a health issue and maybe are on a budget - my advice is this: DONT PURCHASE FROM THIS COMPANY. Their products are cheaper than those sold in the West for a very good reason - THEY DONT WORK. And once they have your money they will - as they did with me - BREACH THE TERMS OF THEIR OWN CONTRACT (mine states that if you can get a third-party out to examine the chamber and they can confirm it doesnt work - they will refund. Well I did that and they still didnt refund). If you live in the West - DONT USE THIS COMPANY. THEY HAVE STOLEN £3500 FROM ME. Save up the necessary amount of money - even if its 3 times more (it will be in the West) to buy a chamber in the West that has been adequately safety-tested, that works and is guaranteed if it breaks down. If you buy from Tecnotu you will not be refunded if your chamber doesnt work. And to be clear regarding ebay - they have removed this company from their website now, they are no longer allowed to trade on there. DONT USE THEM.

Response from Tecnotu Hyperbaric Chamber· May 12, 2025
To whom it may concern,
We would like to present our side of the story in response to a recent complaint that we believe lacks full context and does not fairly reflect our efforts.
The customer initially purchased a 1.5 ATA soft lying hyperbaric oxygen chamber from our platform. Upon receiving the unit, they reported a leak at the zipper. While our chambers are always tested before shipment, and our manufacturing process is mature and trusted globally, we chose to prioritize the customer’s concerns.
To assist immediately, we paid the customer $200 USD toward local repair costs and did not ask for the original unit to be returned. In addition, we sent a brand-new upgraded chamber — a sitting and lying model — completely free of charge. We also sold an external support frame at cost price, purely to help the customer.
We recorded and shared multiple pressure test videos, clearly proving the chambers functioned properly before shipment.
Later, the customer claimed the replacement chamber also failed to build pressure, and blamed the pressure relief valve. Again, we responded quickly by shipping two new pressure relief valves (1.3 ATA and 1.5 ATA) at no cost. These were also personally tested in our factory, with the customer’s name labeled for verification. Videos of these tests were also provided.
In total, we:
1.Paid $200 in repair compensation;
2.Sent a brand-new upgraded chamber;
3.Allowed the customer to keep the original unit;
4.Sold accessories at cost;
5.Shipped new spare parts for free;
6.Shared clear video proof of functional units;
Despite all this, the customer continued to demand a full refund. We find this unreasonable, especially as we have gone above and beyond to resolve the issue. We firmly believe this is not a product failure, but a situation where our goodwill has been repeatedly taken advantage of.
All records, including videos and communication logs, have been documented and will be provided to relevant authorities if needed.
We are a responsible manufacturer and always aim to support our customers sincerely and professionally. However, we cannot allow false accusations and personal attacks to harm our reputation and the trust we have built globally.
Thank you for understanding.
