Poor Customer Service. The product works fine. It is louder than they state it is. The customer service is non existent. First off, they state if you pay with pay pal you get 15% off. Nope, didn't happen. Wrote the company, no response. I've written them regarding the machine being loud. No response. My o2 numbers improved. The product arrived quickly but don't expect any type of service.

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.

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

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

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.
