Someone wrote on how the production was of such terrible quality. I'm great. You also need to be aware that this rubber must be broken in before it can be used properly. After approximately one thousand kilometers, the rubber fully opens up. This occurs when the top layer is worn away and the porous rubber compound begins to work. This compound is what provides the traction on icy and snowy surfaces. Also, keep in mind that miracles do not occur, and you should always make decisions using your head.
