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!!!

Inogen is great especially for travelers Customer Service/Sales was great to work with. I began using my Inogen in the USA and my night O2 levels improved. I was pleased with the machine's portability on my trip to Australia and my ability to use it while in a foreign country.

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.

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

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
