I recently purchased a ceramic cutting tool for my tile installation work in the bathroom. After trying this product, I can say that it has saved me a lot of time and effort. It cuts through marble and ceramic tiles like butter, leaving clean edges. The diamond coating is very durable and lasts longer than other products I've used before. I like that it's reasonably priced too. The only downside is that it's not easy to see where the cut is being made, but I figured it out after a few tries.
