excellent portable concentrator, could be just a little lighter. The strap slides off my shoulder even though I have tried numerous fixes to stop it.

Works well. Would like unit to work at lower temps. Also would like silicon tubing as the current tubing gets very stiff at temps below 40 degrees. I converted my tubing and it is very flexable at all temps.

Good experience with both machines and dealing with personnel.

I like it, but it does bother me that you need to breath though your nose to get the o2. Wish it was constant as other machines are. And mine is one the highest setting and it feels like its not enough at times. If I was on a tank I wouldn't even need that high setting, but with this machine, I need to.

Having used an ultra-quiet G2 for several years, l was disappointed to find the G5 so noisy (and, I feel, with less pump pressure). Several months ago, I wrote a letter to the CEO but did not receive a reply (as a long time Inogen customer who has tooted their horn for years, I should have gotten some sort of acknowledgement). I am very happy with the weight and size of the G5, compared with the G2. But it is noisy so I can’t use it when at several venues (movies, church, etc.).

Gen 4 on standby in car for portability and Gen 5 for home or lengthy travel.

I ordered this portable device for my sister. She doesn't use it very often, but when she does need it, it's the best. It's compact size and rechargeable battery are just what the doctor ordered (pardon the pun)!

I enjoy the mobility that the Imogen gives me. I found the batteries do not last as long as advertised & add a lot of weight. The 2 hour battery is not enough to go any where. The back pack carrier is great! I could get a lot done outside. The balance & weight distribution was excellent. Currently I am having a problem with it not shutting off sometimes. The tec people were very helpful & it worked for a couple of days but is acting up again. Twice it has stopped producing O2 but worked the next time I used it. Need to call tec again.
