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

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.

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.

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.

The unit died the light flashes the… The unit died the light flashes the drops off . Contacted the factory site they told me that unless I purchaseed the unit from their site they couldnt help me. i purchased the unit from ebay from a dealer I thought was autorized from Varon.
