I bought one of your inogen a couple years ago I bought every acc. Plus 2 extra batteries.it worked good for a couple years then it displayed an error I called and they sent me a new one. Within a short time it displayed the same error as the first one.i called this time I was told I didn't buy a warranty so it was going to cost me almost $1400.00. so I bought another brand and it is working good. I will never recommend or buy anything inogen. Ps.i was never told I needed to buy a warranty on the second one . You thank me for the review but not a word about sorry for the inconvenience you created.i lost all faith and respect for your company!!!

My "portable" inogen is too heavy for me to use; I don't know what it weighs. However, I'm 83 years old and weigh 100 lbs; I also have torn both my shoulders' rotater cuffs and have other health problems.

83 year old mother in assisted living has been without her machine for over 6 days. They came and picked up her old one for repair but left her with one with no battery nor charger. Still can't get a hold of anybody. I will not recommend this product at all! everything says just to call them and like everyone else says, you are stuck on hold for over half an hour and then you get disconnected. Find another brand

The poc gave me the freedom to drive again. The first unit was defective, but Inogen took action and the unit was replaced immediately. I am 100% satisfied with my poc .I would buy it again.
