I very much enjoy using my Inogen unit. I have a problem keeping it upright in the passenger seat while I am turning while driving and I very much would like to have some kind of assessory that would help with this.

I couldn't be more pleased as I am with my Inogen1. It has given me more freedom to do things that I enjoy than I had with those large tanks.

From the start, Inogen 's staff has been there for me. I had seen other oxygen equipment suppliers' ad's, but my end selection of Inogen has served me exceptionally well.

I have recommended Inogen to several people where I live. It is my go to source of oxygen when I feel short of breath. Very glad I have it.

I wish I had bought it sooner! The Inogen One G4 System-Freedom #2 has given me the comfort and peace of mind I needed, as a person with COPD, to be able to spend more time out of my home doing the outdoor activities I enjoy. It is so compact and lightweight that carrying it with me is no trouble at all. Bob G., the Inogen rep., thoroughly answered ALL my questions clearly and patiently and made sure I understood exactly what I was getting. Great customer service. Everything was as promised and more. Thank you for helping me improve my quality of life!!
