TrustPilot 5 star review

Very satisfied with my portable…

I am very satisfied with my portable and plug in concentrators. The portable allows me to continue to do the work I enjoy, go on walks, and light exercise. The plug in is quiet and so light weight. It easily travels with me to visit family and go on fun trips with my husband. I am so thankful!

This is the best oxygen concentrator…

This is the best oxygen concentrator I could have ever bought. When I called them the rep rook care of everything, from explaining any questions that I had, to getting the script from the doctor. Now I can go anywhere and always have my oxygen with me.

Freedom!

It’s much lighter weight than the canisters and gives me hours more freedom to do the things I want to do. Love the charging options and being able to track everything on my iPhone. Wish I’d made the purchase sooner!
