Easy to install although one of the chains broke on the first try. A few miles later the first chain broke the link. We heard a broken piece of chain bang against the wheel frame and stopped to see what was going on. A road mechanic came and cut off the loose end of the chain, then the rest of the chain was loose but seemed fine. A few kilometers later, the second chain broke in the same way - the link gnawed through the road surface. This time nobody was around to cut off the chain links that hit the wheel frame, so after a while we just removed both chains - luckily the weather wasn't too bad and the road was just mud, there wasn't any real ice. .
