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.

So happy with my purchase! I am extremely pleased with my purchase. The device works excellently, offering around one hour of usage on a single charge and taking approximately one hour to recharge. It is also lightweight and easy to carry. As a resident of Alberta, Canada, I received my order within nine days, which was quite impressive. To summarize, my experience with the oxygen concentrator has been fantastic, as it arrived promptly and has been functioning exceptionally well.

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.
