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.

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.

Great Portable at a Great Price I’ve had my Varon portable concentrator for a couple weeks now and I’m very pleased with it. I’ve borrowed a friend’s more expensive concentrator before and my Varon performs just as well and costs a lot less so I’m happy. The customer service is also very good. I really believe this company cares about its customers.

Excellent! I could not be an effective commercial truck driver without this device in my SEMI. Everyday, I deal with altitude air pressure changes, dust, and engine exhaust exposure which effect my brain health during the 14 hour work period. Oxygen compressed air canisters aren't allowed so this is the only solution. (CO) Carbon Monoxide (CO) A colorless, odorless gas resulting from the incomplete combustion of hydrocarbon fuels.

Excellent Product Hello, My wife has severe COPD. Having both the room and portable concentrators has been, both upstairs and downstairs, has been a necessity for several years now. The affordability and quality of Varon's units have helped with the quality of her remaining life. Our insurance did cover one unit with a $26.50 copay each month. I cancelled the insurance unit after using one of our concentrators and verifying its quality and reliability for over a year. This has saved me money over the years.
