The actual rubber product is fine. The self-adhesive claim is a complete falsehood. I have yet to find any material that adhesive used sticks even a little bit. It doesn't even stick to itself - which means it isn't an adhesive. In order to use the product an effective adhesive will have to be used and or it will have to be mechanically fastened in place (screws, etc.). Meanwhile the supplier is misrepresenting the product descriptions.
