I purchased a concentrator I purchased a concentrator. It stopped working after 35 days. I contacted the company and they are only honoring a 30 day warrantee although they said it had a 1 year guarantee when I purchased it. One place on the web site states 30 days and another states 1 year. I may have to return it to the manufacturer in China, but right now Oxygensolve is giving zero support

It's easy to use, and I can go out easily. I purchased my own unit about 2 months ago, and I absolutely love it. I also got an extra battery for peace of mind. It's so convenient to switch to the spare battery when the first one runs out, and it only takes seconds. This device has made it much easier for people like me who had difficulty getting out in the past.

Recieved Oxygen concentrator 7 days… Recieved Oxygen concentrator 7 days from order. Machine operates great. I have used it for nearly 48 hours without incident. Remote control unit isn't operating but have not yet contacted company. Pleased with concentrator plan on using on vacation travel, it's about 1/3 the size and the weight of my medical supplied unit.

I have conducted tests on both airflow and oxygen concentration percentage, and they align with the stated specifications. Interestingly, I observed that the power consumption is only 50 watts when utilizing a 12-14v battery/car, which is outstanding and surpasses the specified 75 watts. It seems that the 75 watts is in reference to the 120v AC power supply, and there might be some inefficiencies when using a converter/adapter. Furthermore, the unit does indeed meet the 58db sound level that was advertised, approximately equivalent to the volume of regular speech.
