The origin of the product is from China, Guangdong, which does not make me feel comfortable. I am wondering, if their claim of 30 years of clinical usage is really true, because the parent site says 10 years of focus on ..... If it were really so successful, then we would have heard about it much earlier. And there are many people who asked for the price, but it was never revealed. Even if you go and click that inquire online, all it takes to a page where you can send an inquiry.
I will send an inquiry still, need to see, what kind of licenses are needed to operate this in a commercial venture.
