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 !!

It's easy to use, and I can go out easily. I purchased my own unit about 2 months ago, and I absolutely love it. I also got an extra battery for peace of mind. It's so convenient to switch to the spare battery when the first one runs out, and it only takes seconds. This device has made it much easier for people like me who had difficulty getting out in the past.

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.

Ordered an oxygen concentrator it was… Ordered an oxygen concentrator it was dead out of the box. I contacted them and just got run thru the bushes. Illogical questions, nonsense videos, the damn thing won't start. Finally went to Pay-Pal, they said no problem just send it back to China ($410.00) and they would refund my $285.00. I'll talley this one up to experience. What a bunch of confused turkeys. Yes I'll include Pay-Pal. They offered absolutely no protection. Do yourself a favor an deal with Amazon.

Great price and fast shipping I recently received my NT-5 oxygen concentrator along with an extra battery, and I am thrilled with the purchase. Now, I can confidently go shopping by myself without having to rely on anyone else. The price I paid for the device was Great, and I was particularly impressed with the outstanding shipping service. I placed my order on November 2nd, and it arrived promptly on November 8th, despite the long distance from the West coast to the East coast.
