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.

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

I got the Inogen I got the Inogen. The bedside oxygen did not work. The portable is too heavy. I have been waiting for weeks and weeks to recurve labels to return your equipment. This is ridiculous. I have never had such terrible service. I don’t know what to do to get this equipment returned. I have had many conversations but no action. Please help me. I don’t want your equipment

G5 heavier than advertised G5 heavier than advertised. Given no instructions on connecting tubing for use throughout house for larger concentrator

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.
