Bought the Inogen One G4 with the largest battery for my 94 year old mom. It’s small and light weight and easy for her to handle. The larger battery lasted about 3.5 hours on setting #2

Bought the iongen

The sales rep. I dealt with was fine and knowledgeable. Not impressed with their prices though: 1) I expect a battery that I pay almost $500 for to last longer than 9 months. 2) They want $75 for a power cord that appears to be essentially the same as the ones i buy for my laptops and pay $24 - $29 for. Also, they do not deal with Humana insurance co. so I had to pay for my G4 machine out of my pocket (which so far has worked fine). My wife uses a G3, supplied by a medical healthcare service, and except for the weight, I like much better than my G4.

Love my little light weight machine. It gives me self confidence can enjoy going out more. Just keep your batteries charged and away you go.

Hi! Having just got new unit, I can't really say yet if all is going to be well! I will not know until we are out shopping to see how long unit gives on setting 2! As before I had to down the first one to 1 setting to make it last me one hour! As such I have my backup battery with me as cannot afford to buy more batteries on our limited income which is social security, we are both disabled hubby is 81 years I am 77 years and the hospital caused me to be on oxygen 24/7, but they will not admit any wrong doing on their part! Sorry for babbling on , will let you know how new unit fares in a week or so! I should have ordered a shoulder strap from you at time you were shipping unit as other on broke about four months ago, clip broke! Thank you Cynthia Walton!

I love my Inogen. My only issue is when I have it running for a period of time, such as being at church, the battery become very hot and uncomfortable while carrying it. I also have an issue with the canola .becoming crimped where it connects to the machine. Has to be changed quite frequently

I couldn't be more pleased--my whole experience has been much appreciated! I am so glad I don't have to deal with oxygen tanks, regulators and all the other equipment entailed with oxygen usage--I know because I used to work for United Medical.
