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

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.

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.
