Thank you for resolving the delivery… Thank you for resolving the delivery issue with the portable concentrator battery. After the first one got lost in transit, you promptly sent a replacement, which works perfectly. I would recommend your company to anyone in need of oxygen therapy.

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.

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 purchased this machine for my… I purchased this machine for my brother, who relies on an oxygen machine for his daily needs. It has been a game-changer, granting him the freedom to venture out with confidence. Its compact size and accompanying carry bag make it incredibly convenient, and the inclusion of a car charger for travel is a huge plus. What's particularly impressive is its dual-mode functionality; it switches seamlessly between pulse mode and continuous flow, ensuring uninterrupted oxygen delivery. So far, my brother is delighted with its performance. However, I must mention that the initial machine we received was defective and failed to deliver oxygen. Thankfully, the company's customer service was outstanding. Upon contacting them, they promptly responded and, after reviewing a short video demonstrating the issue, arranged for the faulty machine's return. The replacement was dispatched the very next day. Based on our experience, I wholeheartedly endorse both the machine and the company behind it. Their swift and efficient handling of the situation underscores their commitment to customer satisfaction.

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.
