Needed a concentrator that I could count on.... I was in need of a portable oxygen concentrator and the price was so much to consider, I looked for a long time and then came across the Varon, I weighed all the options and hoped it would do what it said it would hoping the levels of oxygen would be enough. So I purchased it and when I got the machine I had a doctors appointment, took it to the appointment and the doctor checked it out, also put the oxygen level taster on my finger, we did about 5 to 6 laps around the office first at a normal walk then faster up to a very fast speed walk and keep checking the levels and they stayed up to 92 to 93% at all the time we did this. I have used tthe machine for 1 1/2 months now and very pleased with it. The only thing is I wished they would put a longer life battery to the machine without having to purchase the longer life battery, because being on a very low fixed income money don't come easy. but other than that I am very please with the machine.

Varon is a deceptive company which… Varon is a deceptive company which employs the bait and switch technique to rip off customers with generators that cannot produce more than 32% oxygen- far less than any person needing oxygen requires. They ship from china and won’t take returns. Buyer beware of this fraudulent junk factory

Everything like ads The VT-1 is everything advertised and specified on the website. I have tested both flow and O2 concentration percentage and they match the specifications. I did notice power consumption appeared to be only 50 watts when using 12-14v battery/car which is excellent and better than the 75 watts specified. I am thinking the 75watts is with the 120v AC power supply and you get some inefficiencies with the converter/adapter. The unit does live up to the 58db sound level specified, about the level of normal speech.

A quality oxygen concentrator I needed a oxygen concentrator and went the usual route renting a less than quality machine supplied by the local medical company. The machine was old, heavy and noisy a big energy waster to say the least. Varon Oxygen Concentrator fit the bill. Very quiet easy on energy and light no wheels needed. I could not be more happy with my purchase. Jim S
