My Inogen is great
My Inogen is great, I just wish it had more liters capacity. I now need 7-10 liters. I still use the Inogen for when I am just going 59 be sitting and quiet

Great sales people. Donna was awesome. I've referred a couple friends to her and she also treated them very well. I had to have my Inogen One G3 replaced a couple times and the process was seamless. The company gave me no grief and shipped me a new machine overnight. I just put the broken one back in the package and the UPS man took it right then. Definitely worth spending the extra money and purchasing the lifetime warranty.

I am a long time inogen user. I own the original inogen one and it still runs well. I have the inogen 3 and home concentrator. When ever I need service for any unit it is fast and excellent.

It's been a GODSEND! Now I have the ability to actually go outside without fear and really spend quality time with my family....NO REGRETS......

I have been through respiratory therapy and don't need my Inogen as much but it's there when I need it. It was essential when I flew to the midwest. My small in-home Inogen is suitcase sized and easy to transport for overnight proviews.
