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.

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.

Works as advertised Unit came in perfect condition, packed well. Instructions were easy to follow. Unit and remote work as they should. Oxygen level dropped too low while I was sleeping which is why I purchased the unit. This unit has alleviated that problem. I would not have a problem making another purchase.

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.
