Quick, efficient replacement of oxygen concentrator....though limited flexibility by UPS on delivery time. Disappointed that concentrator does not show the percent oxygen that is actually delivered.

I have had mostly good experiences with Inogen. They are very good about sending supplies when needed. The only problem I’ve had was when they kept trying to bill me for a returned unit. After a few phone calls the error was straightened out.

Does everything the manufacturer claims, easy battery recharge system. only negative is the carrying case is very hard to use and could be made slightly larger to ease this concern.

My Inogen One G4 growls like a bear. Cannot take it to church or a meeting because I'm afraid it's loud enough to be distracting. I have called Support but was told that if there was no code on the display there was nothing they could do. I was led to believe this was a quiet unit. Mine is not.

You have some of the quickest service ever! There is a bit of confusion with the telephone people when it comes to ordering parts for the machine. I have called 2x's to get a humidifier line for the floor unit and have yet to receive the proper part! They need a schematic blow up of the machine with the parts shown in position. Easy enough for your design people to create.

The Inogen unit needed to be replaced three times in under a year. So the unit quality is questionable. However, it came with a lifetime warranty. And the company quickly and politely replaced the unit each time. The unit itself, when working, is a lifechanger. It allows freedom of movement not possible with large oxygen tanks, even when they have wheels attached.

We have had numerous problems with our G4. Inogen has rushed replacements to us every time we've had a problem with the product and we are very pleased with Inogen's response. But....are there QC problems with the G4? It seems to be very fragile.....low oxygen, battery problems.

Inogen oxygen gives me more freedom to do more things without having to lug all the big heavy cylinders that I had before. I love it.
