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.

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.

I don't have to be weighted down with… I don't have to be weighted down with heavy tanks anymore and the battery operated package is great. I am concerned about getting in touch with someone in an emergency or need to know situation. It takes 25 minutes or more to reach someone. I am so far, a very satisfied customer.

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.
