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

Response time for inquiries was quick… Response time for inquiries was quick and thorough. We did initially get a defective concentrator. The process for return and replacement was easy. As a retired corporate QA person, things do go wrong with products. It is the response to the issue that defines trust. Varon responded well.

Excellent company. Fast service. I am very pleased with the quick delivery of the unit. It arrived well packaged and well protected from handling and the elements. As far as the instruction booklet, I found it easy to read and comprehensive, clearly illustrated and explained. I couldn’t be more pleased with my Varon Concentrator, It works beautifully and gives me the confidence knowing it is working to maintain needed oxygen at home and traveling. It was worth the price and I value it each breath I take. I would highly recommend to anyone who is considering a quality Concentrator for themselves or a loved one.

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.

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.
