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.

Our contact person was responsive and… Our contact person was responsive and answered all of our questions quickly and completely. The entire process went smooth.

I called for customer service and had… I called for customer service and had long wait times to be told someone would have to call back and they did not - this was on two occasions. The blue tooth on the device, I was told by an IT person-because I could not reach the Inogen people, is non-functioning.

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.

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
