good products My dad needed assurance by having an extra battery when out from his house to help with his oxygen needs. He feels better after trying it now with his extra battery.

Good quality and price. I have had my unit for a month and am very pleased with it. It was packed well and delivered on time. It has really helped me with both breathing and anxiety. I would recommend Varon if you need an oxygen concentrator.

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.

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

Works as advertised Unit came in perfect condition, packed well. Instructions were easy to follow. Unit and remote work as they should. Oxygen level dropped too low while I was sleeping which is why I purchased the unit. This unit has alleviated that problem. I would not have a problem making another purchase.
