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.

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.

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

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.

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.
