I knew pictures of smiling, elderly people out for a casual stroll with their G-5's was an exaggeration (in contract law they call that "puffery"). However, in real life, the unit is fairly heavy, It takes a while to get used to carrying it on your shoulder. That being said, it works.

Inogen concentrator works well, however, it is extremely noisy. The portable unit works well, the batteries do not last as long as advertised. Definitely need to be close to an outlet within 2 hours. Not sure it's worth the cost.

My mom loves her new Inogen machine. It allows her to feel somewhat free again. The reason for the “Somewhat” is because the battery dies too quick and when it dies it sends her in an uproar and she starts to panic and wants to hurry to get home to her oxygen condenser. She is currently looking into getting a longer lasting battery but of course they are much more expensive so hopefully we can figure something out soon.

With G4, I did couple rounds of golf and found it help some way, rated 6 of 10. Double Battery: 2 hrs 12 min/per battery compared to 2hrs 30min as the specs. Usually it takes 4 to 5 hrs/round. Maybe one more battery needed to complete a round. Battery replacement with Hip Pack, it is very hard due to too tight in/out. Oxygen level: inhale about 2-3 % up Noise: A bit larger than expected. Cannula: Quickly bend and clogged oxygen after round.

I really like my unit. The only part I don't like is that the batteries have to be on the unit in order to charge them. All else so far is great.

It works fine... the only problem is that it is very loud at night and feels like it’s warm all the time when charging.

The sales representative was exceptional. She was prompt, informative, not pushy and helpful. Just what you would want in someone helping you to choose a product like this. The unit itself met the need. So far, it has been problem free .Battery life is what was claimed. Only glitch was in delivery. I was promised two day air but unit and told the unit had been sent. In fact, it hadn't been sent and when it was, went out ground FEDEX. I had needed the unit prior to planned air travel and had to delay trip to wait for unit to arrive. Still, it was minor compared to the positive side and I give them 4 stars..

The unit is smaller and quieter than the rental unit I had, so a big improvement. The feature I really would like is a remote power switch. I keep it in my bathroom and wish I could switch it off with a remote control.
