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.

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.

Everything like ads The VT-1 is everything advertised and specified on the website. I have tested both flow and O2 concentration percentage and they match the specifications. I did notice power consumption appeared to be only 50 watts when using 12-14v battery/car which is excellent and better than the 75 watts specified. I am thinking the 75watts is with the 120v AC power supply and you get some inefficiencies with the converter/adapter. The unit does live up to the 58db sound level specified, about the level of normal speech.

I have been using my Varon Oxygen 2 months now.… I have been using my Varon Oxygen Concentrator for over a month now. I am beyond satisfied with this product. I would highly recommend this concentrator to any one who is looking for one. The price is right and the quick delivery.

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.
