Very easy to take on a trip and get through the airports with. I only need it PRN, However when traveling I need it at night and at altitudes above 5500 ft. . The battery life appears ok as long as there is an electrical outlet that you can use after about 3 hours.. A longer life would be helpful at times.

G3 is a little on the heavy side & I keep getting a oxygen error. Followed the directions but no help.

I like the Imogen 5 a lot. I have had a couple of overheating warnings when I've used it on longer excursions but then it cooled down and was fine. Recharging has worked fine, and the bag and backpack are great. It is really great for use as a portable alternative to my home concentrator.

I have G5 so it is not as sweet as the G4. I have to be on 4 liters. The G4 only goes up to 3 liters. It's twice as heavy with the single battery. I have a double battery so it is fairly uncomfortable to use. I use my walker to carry it along with extra charged batteries. I also have an extra charger for the batteries. Even the small G4 is nothing like the commercial. These need to be plugged in when the batteries are low. They don't have outlets in the middle of the meadow by the tree so you can eat a picnic dinner. I actually had to sit in a store doorway because that's where the outlet was. It took a long time. My battery had died and the extra. The only way I had to charge was the machine was to sit there. I had flown for my Grandson's graduation from Marine boot camp so I did not have my walker. It was also when I learned to buy the double batteries and charger. Since then I have bought double batteries. I have 3. And a charger so I can charge outside the machine also. If you spend the extra money to make it work, have a Walker with a basket, it works very well. I love that it blue tooths to my phone and I can see what it is charged at. I am glad that I bought it.

This would be a great machine if I could use it with my C-Pap machine.

light weight easy to use

My machine is much louder than I expected. I actually think the connection between battery and unit is not tight enough. I am happy to have oxygen. I wish it was not so loud.

I wish the unit had a higher output but, overall, I am somewhat satisfied with it at this time. I have had three warranty claims that were handled properly. Beside the fact that I have had three problems in the first year of use, I have a complaint that deals with the most recent problem which necessitated replacement of the unit. I offered to pay the difference to upgrade to the new higher output unit and was told this was not possible as you do not accept "trade ins" even though you were sending me a new, replacement unit.
