The product broke down after less than 6 months Most of these reviews have to be bought. I purchased a unit a little under 6 months ago. It started over heating to the point of it smelling like fire about 3 weeks ago. I have not been able to use it since. Their customer service is obviously in some Asian country and they do not care, they provide no solution and no help. They just say they will give me a 20% discount to buy another unit. Why is this company selling in the US a medical device and they will not provide any support? The way this company acts I doubt this even produces any oxygen at all.

Very quite device It took me awhile to use it I wanted to get extra O2 tubes and something to clean them with. It is quieter than I thought it would be - I was using the nasal cannula wrong no instructions for that - I love the machine it helps me almost every night, so glad I have it - I would suggest a different hose connector though one that is tapered so it is easier to put the tubing on bless youall.

good products My dad needed assurance by having an extra battery when out from his house to help with his oxygen needs. He feels better after trying it now with his extra battery.

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.

Good quality and price. I have had my unit for a month and am very pleased with it. It was packed well and delivered on time. It has really helped me with both breathing and anxiety. I would recommend Varon if you need an oxygen concentrator.
