I recently purchased the G5 portable oxygen concentrator with the double battery. I received excellent guidance and assistance from my sales rep, Darrin M. Shipping (to Canada) also went quickly and smoothly (the missing backpack in the order was quickly sent in a follow-up shipment). The unit was easy to assemble and charge. I use the POC only in the backpack for walking distances (from 1 to 5 km) and have been pleased with it although I do notice the extra weight (I am a small person weighing 42 kg (about 90 lbs). After using an oxygen tank (very uncomfortable), I was taken aback by the noise of the POC but am getting used to it (and it is muffled somewhat by the backpack). I will purchase the single battery once it is again available to reduce the weight since I generally only need the POC for an hour or two at a time. I find carrying the POC in the shoulder bag uncomfortable and awkward and would not walk distances with it. A machine with the capacity of the G5 (6 l per min) but the smaller size of the G4 allowing hip carrying would be great. For me, a better POC would be all about reduced size and weight (challenging I know). Appreciate the well-built machine and good service from Inogen.

My husband likes his Inogen. It's small, compact and much easier to take compared to the large tanks he was first given.

I have only had the unit for a short period and have used it twice. I would like to see the battery life on higher settings last longer. I have a double battery but only last 5 hours on the 3 setting. All in all the times I have used it the unit has worked satisfactorily. I look forward to going out more now that I don't have to haul tanks.

works good for about 4 hours, and then it starts beeping

The G5 that I purchased is a nice unit. It performs as expected. With the larger battery that I got and in the carry bag it's a little over 5lbs. The carry strap is very adjustable but the detachable pad (Velcro) that you put on/over your shoulder could use more padding and be a little larger. It is as quiet as advertised and the only thing you really hear is a slight noise while it's running and a low popping sound every few seconds which is common in oxygen concentration units. My one big complaint is that the unit draws down the battery if it's not in use. I've found after recharging it to 100% that if you don't use it for a day to two the power drops down to like 97-98% when you turn it back on. It would probably drop more over a longer time of no use.. So it's best to remove the battery if you don't plan on using it for a few days. I'd also have to estimate, at least for the short time I've had it, that the length of time the battery will last may not be as long as claimed. I use mine on a setting of 2 and what I've seen the power level drop down to after like 2-2.5 hours of use when I recharge it makes me wonder how long it will last until it runs out of power. The other issue is this unit, and really all brands and models of these units, is that they are expensive! And Inogen just had a price increase so I was glad I got mine before the increase as it was outright purchased. Also the accessories are way overpriced. All of this is typical of medical equipment. I got mine right from Inogen and the sales rep I had was fantastic.

This is definitely better than carrying an O2 tank, but it's not perfect. The single battery is useless, lasts less than 90min. It's not silent, quiet enough for a restaurant ,but church(?). Overheating can be an issue, be careful were you carry it or set it down (not in your lap).

Inogen has helped live my life without dragging a tank behind me. Its so light and easy to carry. I would recommend it.

I like that I don't have 50 ft of tubing running around the house. I have a foot wound healing,so I roll around the house in a wheel chair and hang the machine on the back.very handy. However,I will say the machine is heavier than I thought it would be. The battery is very heavy.it isn't a big deal except in dealing with weakness due to anemia. Overall,very pleased with my G5.
