Thank you for resolving the delivery… Thank you for resolving the delivery issue with the portable concentrator battery. After the first one got lost in transit, you promptly sent a replacement, which works perfectly. I would recommend your company to anyone in need of oxygen therapy.

Better breathing on the go with Varon 3L/NT-05 We received our Varon 3L/NT-05. This little machine is exactly as described. My husband had used a different one in the past, but it was so heavy he had trouble even walking with it. Now with our Varon he has a much easier time carrying the unit. I did notice that the carry case had a defect on the velcro flap. I contacted the company and their response was very fast. They have already shipped a replacement case. So glad we discovered this company. Now we can go on our trip and my hubby can climb the hills with oxygen pulsing into him. Highly recommend the Varon 3L CFOP!

So far So far, so good! I've only had the unit for 4 days, but it seems to be working well. A friend of mine wants to order the same NT-03 model, and I might gift one to him for being such a helpful friend. I'll need more information from him to confirm if this is the model he wants.

I purchased a concentrator I purchased a concentrator. It stopped working after 35 days. I contacted the company and they are only honoring a 30 day warrantee although they said it had a 1 year guarantee when I purchased it. One place on the web site states 30 days and another states 1 year. I may have to return it to the manufacturer in China, but right now Oxygensolve is giving zero support
