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.

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.

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.

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.

Better breathing on the go with Varon 3L/NT-05 We received our Varon 3L/NT-05. This little machine is exactly as described. My husband had used a different one in the past, but it was so heavy he had trouble even walking with it. Now with our Varon he has a much easier time carrying the unit. I did notice that the carry case had a defect on the velcro flap. I contacted the company and their response was very fast. They have already shipped a replacement case. So glad we discovered this company. Now we can go on our trip and my hubby can climb the hills with oxygen pulsing into him. Highly recommend the Varon 3L CFOP!
