I bought a VARON New Arrival VT-1 3… I bought a VARON New Arrival VT-1 3 days ago. I have not received the VT-1 yet, but I have received the VH-3. The VH-3 is everything advertised and specified on the website. I have tested both flow and O2 concentration percentages and they match the specifications. I use the concentrator at night in conjunction with my Resmed AirCurve 10 ASV pap machine to mitigate central and sleep apnea and the VH-3 appears to be doing the job of helping to keep my SPO2 levels in the 90's as opposed to the mid 70's without. I have used a recording pulse oximeter overnight with both. The VH-3 replaces a large Phillips unit that is much bigger and noisier. I am looking forward to testing the VT-1 and using it while traveling. Please feel free to use this information, without identifying me

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.

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.

The VT-1 fulfills all the claims and… The VT-1 fulfills all the claims and details mentioned on the website. 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.
