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.

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.

Staff was very knowledgeable and… Staff was very knowledgeable and answered all my questions and concerns.

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

Inogen is excellent I’ve used several portables but always had difficulty because they used carts and were terribly heavy to load and unload in my car. My new Inogen is wonderfully light and so much easier to use. The sales person at Inogen was wonderful to work with and I’m extremely pleased I bought this unit. Thank you Inogen!
