I purchased one of their units and O boy what a ripoff I purchased one of their units, after I received it I tried it and realized it was not going to work for me. Since the unit had a 30 day return policy for a full refund, I started trying to call their listed customer service number and found out later in an email that their phone number wasn't working! Then after 9 emails they finally gave me a Rma number and the shipping address that was in China I attached a label and took to UPS where I was told it would cost 400 to 500 dollars to ship it to China which exceeded the purchase price of 351.10. So it's a ripoff if you ever need to return it for credit or service!! What a rip-off!!! BUYERS BEWARE !!

I bought a VARON New Arrival VT-1 3… I bought a VARON New Arrival VT-1 3 days ago. I have not received the VT-1 yet, but I have received the VH-3. The VH-3 is everything advertised and specified on the website. I have tested both flow and O2 concentration percentages and they match the specifications. I use the concentrator at night in conjunction with my Resmed AirCurve 10 ASV pap machine to mitigate central and sleep apnea and the VH-3 appears to be doing the job of helping to keep my SPO2 levels in the 90's as opposed to the mid 70's without. I have used a recording pulse oximeter overnight with both. The VH-3 replaces a large Phillips unit that is much bigger and noisier. I am looking forward to testing the VT-1 and using it while traveling. Please feel free to use this information, without identifying me

Recieved Oxygen concentrator 7 days… Recieved Oxygen concentrator 7 days from order. Machine operates great. I have used it for nearly 48 hours without incident. Remote control unit isn't operating but have not yet contacted company. Pleased with concentrator plan on using on vacation travel, it's about 1/3 the size and the weight of my medical supplied unit.

So happy with my purchase! I am extremely pleased with my purchase. The device works excellently, offering around one hour of usage on a single charge and taking approximately one hour to recharge. It is also lightweight and easy to carry. As a resident of Alberta, Canada, I received my order within nine days, which was quite impressive. To summarize, my experience with the oxygen concentrator has been fantastic, as it arrived promptly and has been functioning exceptionally well.
