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 !!

Excellent oxygen concentrator I am currently using the NT-04 oxygen concentrator and it is an excellent machine. It is lightweight, quiet, and offers seven oxygen settings. The price is also very reasonable. In fact, I am using it while typing this review. I recently received my NT-04 and I am extremely satisfied with its performance. It quickly raises my oxygen levels to the level recommended by my doctor for someone my age with asthma. Overall, I am glad I made the decision to purchase the NT-04 as it has proven to be a great solution for my needs.

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 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.

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.
