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 !!

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.

We ordered a Varon VP2 machine 10 days… We ordered a Varon VP2 machine. 10 days later, we received an NT2 machine, which is an older model. We tried calling. Mailbox full. We tried texting. No response. We tried email. No response. I am going to contact my credit card company. A 2023 press release states that the VP2 is a new model.

I recently purchased the NT-05 portable… I recently purchased the NT-05 portable oxygen concentrator and it's been working well for me. Although I had an issue with the charger, the company sent a replacement promptly. The battery lasts for about 2 hours, and their customer service is exceptional.

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.
