There are indeed many fake and shoddy things purchased online, and of course there are also really cheap ones. This really needs to be distinguished carefully. In fact, normally speaking, this issue should be supervised by regulatory authorities, and consumers should not be allowed to identify genuine and fake products by themselves. According to laws and regulations, the items sold should be of high quality and quantity. But now there is no supervision, so you can only decide whether it is good or bad by yourself. And there is no room for explanation when problems arise. You can only be careful. Once you are fooled, most people can only consider themselves unlucky.
