These work great and make it very easy to control on ice and roads, My only complaint is the angles on the front area could have been ground down to minimize snags on concrete edges or things like railroad tracks. I ground the front area down a little to smooth the ride over these edges. I have had them snag in the past. Also there was a lot of welding flash (small balls of metal on the bottom side so I ground that off and repainted the Carbides. Overall a very good design that I like but some of the detail work could be better.
