THE TIGHTENING PIECE BEHIND THE HEAD… THE TIGHTENING PIECE BEHIND HE HEAD KEEPS LOOSENING AND NEED TO BE TIGHTENED. I'M THE HUSBAND AND IF I'M THERE, I CAN TIGHTEN IT. OTHERWISE, SHE'S STUCK. IS THERE A CURE? ALAN L

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

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.

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!!!

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.
