The blue tooth on the device, I was told by an IT person-because I could not reach the Inogen people, is non-functioning.

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.

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!

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.

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
