Easy Usage I enjoy my G4 and the freedom it gives me. I’m 93 years old and find it easy to operate. The questions I have asked of customer support have all been always been answered and the representatives have been courteous. Thank You.

the sales guy was great but i bought… the sales guy was great but i bought too soon. hit the road so it was a month before i could try it. easy set up. but no one told me that the system has a 5-6 sec cadence of a repetitive 'pop'. Super annoying. sales support good. follow up good. gatekeeper answering service is an idiot who kept me from buying for almost a month.

This was the best company I have ever… This was the best company I have ever dealt with! My previous oxygen provider ignored three prescriptions for a portable oxygen concentrator from two pulmonologists. The Inogen team handled all of the insurance requirements. They are now my provider for all oxygen needs. The portable unit is simple and functions perfectly for my needs. Thank you to everyone at Inogen for the great experience.

Inogen is excellent I’ve used several portables but always had difficulty because they used carts and were terribly heavy to load and unload in my car. My new Inogen is wonderfully light and so much easier to use. The sales person at Inogen was wonderful to work with and I’m extremely pleased I bought this unit. Thank you Inogen!

Before getting the Inogen we were… Before getting the Inogen we were always worried the portable oxygen machine that we had would quit working while we away from home, which it did several times. Not only does the Inogen work really well, the batteries last long and we are starting to relax when we have to go places further from home. We haven't had any problems with it. Just wish we would have gotten one sooner
