Reasonably Priced,Highly Recommended I received my oxygen concentrator NT-02 a few days ago and I am pleased to say that I am impressed with the product and the company. I purchased the unit for $799 and it has exceeded my expectations in terms of performance. I have struggled with COPD and in the past, I purchased a different brand that did not work as well. Due to my lack of insurance, I had to leave the hospital against medical advice. I decided to take a chance on this machine and I consider it to be a win. It helped me recover and provides high-quality oxygen when needed. I was able to get my oxygenator at a very reasonable price and it works great. I received it a week ago and I am very happy with the quality. I have already recommended this product to others.

I bought the 3-liter continuous flow… I bought the 3-liter continuous flow machine less than a month ago, and so far, it's been great. It was well-packaged and is functioning perfectly.

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

So far So far, so good! I've only had the unit for 4 days, but it seems to be working well. A friend of mine wants to order the same NT-03 model, and I might gift one to him for being such a helpful friend. I'll need more information from him to confirm if this is the model he wants.
