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.

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.

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.

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.

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.
