System works very well
System works very well, is quite and, the in-home uses less electric. The portable is truly portable, as it is lighter than others currently on the market

its hard to be on oxygen every waking moment, but if you are like me, you savour the moments, the fact you can still have a life...thanks to my INOGEN G4 I can go anytime, and not worry, I bought extra batteries so im comfortable being gone all day... its expensive, but so worth the expense....I would heartily recommend it...

I have been with Inogen for a number of years now. Representatives are always professional and I love the fact that my portable is FAA approved. I don't have to wait a long time when I order supplies or something goes wrong with my concentrator. Currently I am on 4 liters. I wish you had a portable that's a little lighter weight and last longer than 5 hours.
