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.

My disappointment with Inogen… My disappointment with Inogen continues. I can add another unit failure to my experience. I been thru a half dozen G5's that have failed and had to be replaced. The authorized seller I've bought from has been great and understanding. Every failure has been after less than 100 hours of use. I even had a brand new unit fail after only 4 hours of use. I don't trust these POC's. If you are considering purchasing an Imogen product I would recommend adding the cost of a lifetime warranty (about $500) to the cost of ownership. The one thing I can count on is the unit failing. Soon I will be past warranty and stuck with a $3000 paper weight and needing a POC. I would not recommend Inogen concentrators but if you do buy, get from a authorized dealer and not direct from Inogen. ------- I see I received the standard canned response from Inogen. Unless you would consider supplying a unit that will not fail or give me a free lifetime warranty, I see no reason to talk. Every time I return a unit, it costs me $89 to have a replacement shipped.

Erica was more than helpful Erica was more than helpful. I appreciated her so much. The Inogen system has given me so much freedom. I love it♥️

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.
