I almost do not buy, because here is a review in the chain is to be mounted on the rear axle of the BMW 5 Series with great difficulty. I can not confirm. After watching the video on the manufacturing side to me the first dry run succeeded in about 5 minutes. Dismantling much faster. Sure it will be more difficult in the snow. Nevertheless, I managed the installation much easier than my previous ring strap chain on the previous vehicle. (But I am not a professional. Snow chains I have so far used only 2x.) The motivation for the review was the poor classification by another reviewers for BMW 5 Series! When I drove the chain in the snow I'll still resent my experience in this regard.
