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.

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.

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.

I own 2 VP-1s I own 2 VP-1s; 1 VH-1; and two VH-3s. The value for the price was initially excellent. But after a few months the VP-1 started beeping, meaning "low concentration". I cleaned everything, still beeps. I switched to new tubing, still beeps. There is nothing wrong with the air flow, but it still beeps. So the good investment is now a waste of $600. I tried the customer service phone but mailbox is full. I filled out the service form yesterday, no response so far.

Fast and fair company to deal with. The unit arrived very fast. It worked beautifully except I couldn't get it to work off the battery. It didn't seem to charge. I reached out to the company and they sent a replacement battery right away. It works great now and I appreciate the light weight machine. I went out with it today and everything worked just fine. I would recommend this to anyone in need.
