I have been a customer since 2014. I had an issue with my new Inogen One G5. The company responded within 12 hours to resolve my issue as best they could. I was very impressed with their compassion and prompt service.

Sales person was great. I have the oxygen conentrator for home. I would have wished the on/off button was larger and more pronounced (bulge up more) because with my older oxygen concentrator I did not have to turn on the light to turn it on or off, but I do now.

I opted to purchase not rent the Inogen machine, I have a 2 1/2 hour battery and a four hour battery. I wish that they had a little bigger battery for airline traveling.

I had a problem with my Rove 4 and they were very expedient in replacing my unit with a new one. No run around or questions asked I was informed to watch UPS for delivery of the new one.

The agent that handled our order was great. She took time to explain everything and answer every question we had. She never rushed us and that is why we decided to purchase the Inogen. Once we received the machine, it was simple to set up. We love it. It's so much easier to carry than dragging oxygen tanks everywhere. The battery lasts close to 4 hours and it comes with a car charger. This little machine is well worth the money.

I’m very happy with my Inogen performance, I have not had to use any of the tanks I have on hand since receiving the unit.
