It depends on what kind of conditions you have. They will hold up well in marginal snow as long as it's just snow. Throw in a little sand like we get in Michigan and they're a waste of money. The sand will eat the teflon faster than the plastic. A few years ago I had a set on my sled. We were up in Michigan and there was some sand mixed in with the snow because the ground never got a good freeze before the first snowfall. The first day I made a 140 mile round trip and my hyperfax sliders were toast., I figure that was a bout *$1 a mile. I'd say save your money.
