You must test things multiple times to ensure they look good.

The snow chains I ordered were size S, which is meant for tires up to 205cm. I was sent the larger size. Because of this, I can't put them on my 195 cm tires. They are too big.

Received the item within a week! They look and feel good. You need long pliers or something similar, like the claw tool I used, to get the belt around the tire. Once mounted, they hold securely, and a ratchet will be helpful. There's no snow currently, so I can't test them, but they should definitely work if you get stuck in the snow.
