As someone who relies on oxygen therapy daily, I've tried both rental units and other portable brands before, but this has been one of the better experiences I've had. The machine is dependable, and really lightweight, much easier to transport than older models. Thank you varon

Ordered & Received The Oxygen Concentrator(with all attachments needed). Easy to setup, really quiet. I got this for my elderly pup🐾🐾❤️. I am pleased with my purchase.

Battery will die then what. You die. Don’t leave it plugged into car charger. When new cars are off they kill the portable batteries. Live and let learn or die and let learn. Probably same goes if you plug in ac out let and unplug the wall but leave it plugged into battery. So it sucks watching someone gasp for the needed air for 399. Unhappy customer here and ask for credit card info to help but say it will be refunded. Nope pass

I've been using the varon oxygen concentrator for several weeks now, mostly at home and occasionally during short trips. The machine has been performing very well overall. It took me a little time to get used to the pulse delivery at first, but now it feels ok. The size and weight make it easy to carry around, and the bag that came with it has been really helpful. The battery life isn’t quite as good as I expected, but I did get an extra battery during the sale, so it hasn’t really been a problem for me.

I have a NT-08G. I also have a INOGENONE G4 and a INOGENONE G3. I use the NT-08G all the time. The inogenone G4 It has been replaced once it over heats during the Summer here in Las Vegas, NV and the inogenone G4 is way heavy. I Love my NT-08G. It's not heavy or noisy like my inogens and it don't cost as much as the inogens. It was like 1/3 of the cost I paid for the inogen. Thank You Roger Lockwood

I got our unit in May and had nothing problems. The battery didn't hold a charge to get to a doctor's appt and back. Then the unit was stuck on 5 liters when only 3 was necessary. Customer service was no help, they stated that we'd had it too long to do anything about it. Would not recommend this company!!
