Lightweight Portable Concentrator
The Inogen G3 concentrator provides me with a low weight solution. Not only is this the smallest portable I have seen, it is also the least weight--less than 5 pounds with the battery. It takes a few minutes to get the concentrator to ramp-up to the desired concentration level. Three sixteen cell batteries will keep the concentrator going for a full 24 hours!

Great Machine but no support
Great machine. The Inogen G3 is a lightweight solution and I would recommend it. However, both Inogen and Vitality Medical offer little to no supporrt if something is wrong, even when Brand new. Had to buy a replacement part (BA306) from another supplier after weeks of complaining the original part was defective.

Good, with one Exception
We are disappointed with the "popping" sound the Inogen makes. It will not be suitable for church, movies, etc. because of this noise. Also, the stated weight was somewhat misleading since it is shipped with the larger battery which is considerably heavier than 5 pounds. So we had to order the smaller battery.

Big improvement to the Inogen G2
The new Inogen G3 model is much smaller and less weight than my old G2. It does seem just a tad louder than the G2, but it is a great trade-off for less weight and smaller size. I absolutely love the carry bag design, almost like a wrap-around skin for the concentrator.

Every I had Hoped For!
I have had my new InogenG3 for a couple of weeks now and I am happy to report that it is everything I had hoped for and more! I already had a portable that weighed 10lbs but even though it was equipped with a shoulder strap, it was too heavy for me to carry and I had to use the cart to pull it around. I wanted a little more freedom and convenience and I spent a great deal of time researching my options. What InogenG3 offered seem too good to be true but I went ahead and ordered it and hoped for the best and that's what I got... the best! I highly recommend it!

Excellent.....more than I expected
I'm 68 years old and never saw this coming....The Inogen One G 3 is a great
unit light weight, east to use and carry...I elected to purchase the backpack. It's a
breeze to use....We cruise a lot and use it 24/7....Vitality Medical receives a better rating than the Inogen One....Have already recommended them to a friend....6 weeks and 2 cruises

Lighter weight but louder.
It is lighter weight which is what I was looking for, but it's much louder and I miss the handle on top like the G2 which enabled me to carry it without being in the black bag. Not sure I would recommend it over the G2.

The only problem I have experienced so far is a recurring message that the nasal cannula is not connected properly. Ihave tried a couple of different cannula and this problem continues to come up several times per day. Otherwise this G3 seems to have been a very good purchase for me.
