Initially, the idea behind AliBaba was good, and they did work well. But at a certain moment in time they started having more and more scammers, who sell fake shit, and low quality stuff. To their honor I got to say that they do take care of reimbursing the money and so on, but this is just additional pain in the ass. So I regard AliBaba as a good place to get some small cables, or something like that, but definitely not as the place to get things that you will put into yourself. You don't want to be putting some fake cheap supplement into your body. The risk ain't worth it in my opinion.
