Inogen is great especially for travelers Customer Service/Sales was great to work with. I began using my Inogen in the USA and my night O2 levels improved. I was pleased with the machine's portability on my trip to Australia and my ability to use it while in a foreign country.

I love the convenience on how portable… I love the convenience on how portable the unit is. The quietness of operation and the concentrator is great also.

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.
