G3 is the best lightweight portable I have ever used. Easy to operate and transport, excellent advice and back up from Pure 02.
I used this G3 for my recent 3 week stay in Canada travelling with my sister. The machine is brilliant, lightweight, easy to charge and operate. I took 2 small and 1 large battery with a desk top charger too. It is compact and easy to take on board flights and take to hotels etc. I am a petite 4' 10" and all the other portables are so heavy, this was a delight to carry in comparison. I thought the rental cost was very reasonable whilst the service from Pure 02 was friendly and efficient. Now saving up to buy my own machine. Review by Karyn / (Posted on 11/4/2015)
Excellent product and service
The Inogen 3 is by far the best and lightest portable oxygen concentrator for 4L that I have used. It is so versatile with being to change levels at the touch of a button and just a few moments to change battery. I used my Inogen 24/7 for 5 weeks whist visiting New Zealand. I have 1 sixteen cell battery and 2 eight cell this covers me for all eventualities - delays at airports etc. I would also suggest purchasing a desk top charger as if I have any reservation it is that the recharging of batteries is rather long winded.

At last a small machine that gives higher volumes of oxygen. This is been a winner at my therapy centre! (Originally posted May '14)
Review by Gee / (Posted on 8/27/2015)
Hired one for a holiday in France as I was quoted price of £800 for local supply of oxygen bottles./ So pleased, I bought an Inogen on my return. The NHS O2 bottles are so heavy and cumbersome and impractical for holidays. Would not be able to go away without the Inogen. Very happy man (Originally posted September '15) Review by Richard / (Posted on 7/23/2015)
