Portable Oxygen Generator System for Home & Outside & Driving & Traveling Use

I do have a lot of doubt because this health product was sent directly from China without any US health standards inspection or quality control. I do not mind Made in China stuff, I do not want to use any products, especially health-related products with unknown origin. The shipping is also slow, I probably can get the similar products with faster shipping time and was properly inspected.

This oxygen generator very poorly gives off oxygen. It is not portable the way it is described on the website and is a bit confusing how to use and how it properly works. I would not recommend to buy if you're looking for a portable generator for oxygen.

We received a defective product. I contacted customer support and they replaced the machine right away!

This item does not work. I tested the air in an enclosed environment with an oxygen sensor and there was no change. I request a refund and mailed the item back but still have not received a refund.

I got hit recently pretty hard with Covid. Picked this up to help my lungs out a bit when sleeping. Attached it to my cpap and put on 4l lowest setting. My lungs felt ton cleaner after the first night. Not a cure obviously for Covid, it but seems to help. I continue to use it for shortened periods for afternoon naps as I am sure there is sometimes significant rebreathing of exhaled air wearing a full cpap mask.

Lasted until right after the 30 day warranty ended. Flickers on and off. Maybe the power supply crapped out. For the price I paid this is rediculous.

Purchased and sent back two of these. First sent back would not turn on. Second sent back had no air coming from machine. Did not order a third machine.

This thing is heavier than you would think and not as easy to move around. It seems like pretty basic quality
