The body of the sled is pretty stout. There are a couple things that could be better. 1. The rails are hard to adjust because the screws end up behind the wheels or at least close enough it takes small hands and some finagling to tighten the screws. 2. The wheel path ends up with lots of saw dust and if not cleaned continuously, the sled can ride up and down and the saw dust leaving ridges on the wood. 3. Saw dust gets in the router base track and creates chattering sometimes.Of course all these things can be overcome by just keeping the area clean.
