Not bad at all. I cut ceramic tiles like butter. I know it's not very impressive since it's only ceramic. But he performed cleanly; without chips. I cut through the marble countertop with relative ease. I've used a water trap to keep the saw cool and it seems to wear it out just as well. Cons: Some of them had more hits (jiggles) than I expected. Handyman. I don't expect them to last very long; However, I didn't pay enough to be a problem for me.
