Shipping and product properly! Have the chain bought this winter for ski and there also equal to brought into use, since our accommodation was only accessible through a snow-covered private road. Although we have drawn up for the first time chain, the assembly with the enclosed (water-resistant) manual has well and works fine (difficult it could be, however, if you hang up the chains in the dark and for the first time). But you must certainly not be a home mechanic that to make the. Who is his technical skill is not so sure, if necessary It is easier if you try mounting a tire first in peace at home (the second time the installation is certainly faster). Function does the whole then properly. Even after multiple trips she sits chain still properly without tightening again.
