Has anyone else had problems with Rotozips? I've been through 3 of them in the last few weeks. I bought the one with the right angle attachment so you can run small cutting blades on it. The first 2 died while cutting aluminum siding. Both times I returned it and got another. I eventually got the job done with them. Now, I go to use it to cut 1/4" deep grooved in pavers, so I can break them relatively straight. I got about 4 of the bricks done and the thing just died. I was not forcing the tool, simply letting it glide and make the cut. It comes with a masonry bit, so theres no excuse for it not to work. Looks like I will return it again.:furious:
