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 only complaint I have is the cannula attachment kinking. I wish there was a spring that would support the tubing where it attaches. I’ve mentioned this to Inogen, but was told they have had numerous concerns. Robert Oliveri

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.

The Inogen mobile compressor made it… The Inogen mobile compressor made it possible to be out and about again. The battery life is greart 4and easily recharged. Only gripes, heaviness and noise, particularly at church.

Great product with one tiny flaw Great product, took my Inogen home on a holiday and it was small and convenient enough to carry to the hotel. The service for setting up the machine was great and the sales team made sure that the international shipping went smooth (purchased in Canada) and in a timely manner. Only one improvement could be made: the air exit nozzle points upwards, so with gravity the air hose can fold over and obsruct air flow. My previous oxygen generator has the nozzle come off horizontally thanks to a 90 degree bend.

I tried to get my PCP to order… I tried to get my PCP to order supplemental o2 for 2 years. Finally I got him to sign the paperwork so I could purchase it out of pocket. It's a good thing-we are traveling to visit family in Colorado and the altitude here is 6600 feet. I am using my Inogen continuously, otherwise my spo2 would be in the 80s all the time. I have no shortness of breath with my o2 on and my spo2 stays in the 90s. What would have happened to me on this trip if I did not have supplemental oxygen? The moral of this story, trust your women's intuition when you think you need something! THANKS INOGEN!!!
