The continuous flow is steady, the controls are simple, and the machine is much lighter than the oxygen equipment I used before. The battery lasts long enough for errands, appointments, and short trips, and it also works well in the car. I’m very happy with my purchase and would recommend it to anyone looking for a dependable portable oxygen concentrator.

Compact and portable. Delivered on time, as promised. The original battery doesn't last very long. That's a shame, because larger batteries are quite expensive.

It does have a whistling sound when it's working, which I'm not happy with. I'm glad I bought two batteries because one wouldn't have been enough for me. I'll definitely be buying another one.

I purchased this for my mother and it was a life changer for her. She can move around her house with ease and finally has her life back. I was really happy with the purchase and the customer service was stellar. I highly recommend using this website for purchasing portable oxygen concentrators. They have the best prices in the market for brand new equipment. Thanks again for making my moms life better. She's finally seeing a physical therapist which is helping her tremendously. This wouldn't of been achieved without the great deal I got from this store. I will be buying batteries in the future when the time arrives.

My grandmother has been having trouble breathing these past few days, with her oxygen saturation at 85. She's been using this machine, and she's been using the 1L. She used to be afraid to leave the house, but now she carries it with her wherever she goes.

This portable oxygen concentrator has a shoulder strap and is lightweight and is easy enough for me to carry. Now I’m able to breathe when I leave the house. I also like the fact that I can bring an extra charged battery when my oxygen is low. The battery is very easy to replace.
