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.
