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.

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

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.

Very surprised to see positive reviews… Very surprised to see positive reviews of a company I know to be deceptive. Bait and switch is how I’d characterize them. Their advertising goes on and on about 90% oxygen concentration but their entry level is only 30% concentration which is not something they tout prior to the sale. Be very cautious when dealing with these folks, they will ship you something from China which you will never be able to return and they will offer you a small credit to shut you up.

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.
