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.

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.

I have conducted tests on both airflow and oxygen concentration percentage, and they align with the stated specifications. Interestingly, I observed that the power consumption is only 50 watts when utilizing a 12-14v battery/car, which is outstanding and surpasses the specified 75 watts. It seems that the 75 watts is in reference to the 120v AC power supply, and there might be some inefficiencies when using a converter/adapter. Furthermore, the unit does indeed meet the 58db sound level that was advertised, approximately equivalent to the volume of regular speech.

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.
