Although I’m extremely happy to have the freedom to get out with my portable concentrator, I am not happy with the batteries. When I first received my Inogen 6, the battery only lasted a little over four hours. I called and was sent a second battery. The second battery only last 4 1/2 hours. I feel like that is not exactly what I thought I was paying for now when I go out and not knowing exactly how long I’ll be, I carry the second battery as a back up. Also two weeks ago I charged both batteries up to 100%. Today when I’m getting ready to go out, both of them are down to less than 80%. I am not a happy camper.

Send an email a few weeks ago because even though the website said that the filters should fit the machine we have, they don't and I needed to know what the exchange policy was. Also needed to know who I can send the machine locally to since it's a first generation to get the cylinders replaced. Have not heard any reply to my emails

Mr. Steven N.
The 1:1 personal instructions were excellent, showing me features & settings that I was unaware of. This initial training was outstanding.
