It is noisy but it provides portable oxygen and that gives mobility that I wouldn't normally have. Were it not so noisy - I would have given 5 star.

Works, higher levels reduce the battery life significantly, however , at 3 liters, 2double batteries will set you more free than any other option that I know about.

I ride a bicycle and the tower needs changing in six months we’re you say 12 to 18 But the machine works great 👍

I did need the use of my Inogen 5 concentrator it work fine for my use I was on level 3 of oxygen (sorry my terms might not be correct) but having it always comforted me knowing it was right there for use as needed I used the double battery didn’t really use the singles much but the weight is was much heavier but the use is way longer so far the unit is working fine it’s been almost a year since buying it haven’t used it in last few months tho the only complaint I have was the price of it and extra stuff for it like batteries they are extremely high in price and me being very knowledgeable on batteries it doesn’t make since except for corporate greed but other than that it looks like I’m pretty happy overall I believe if you need an O2 concentrator Inogen is the one to buy if you can afford it I barely could and I’m still making payments on mine for another year unfortunately but those are the cards we're dealt Good luck with your life - wil

much heavier than advertised , can not use a belt carrier. Back pack eventually gives back ache. OK if you only use one of your two hands to perform your daily outside activities. J Perfect

Great unit no problem with it at all. The only gripe if any is the accessories, such as the external charger and extra batteries are too expensive. thanks

I AM AN OLD MAN 81 AND ONLY NEED TO USE IT AT NIGHT. AS MUCH AS I LIKE MY MACHINE , IT IS QUITE NOSIEY AND WILL AT TIMES WAKE ME. I CALLED TO SEE IF IT WAS SUPPOSED TO MAKE THIS MUCH NOISE AND THEY SAID YES. I CAN'T BELIEVE THAT HE WAS RIGHT. IF I SEND IT BACK THEN IN WONT HAVE MY OXYGEN AT NIGHT,

I feel the unit is a little heavy,er then I expected it to be. However it does do a good job and supplies Oxygen for at least a 5 hour period. Over all it is a nice unit, I have the G5
