Worked great until it failed
I bought this tool to remove tile in my shower. For a couple hours, it worked fantastic on the hammer function. But then it just stopped hammering. The chisel would vibrate mildly, but not enough to do any good. After moving it around at different angles and letting it run, it would occasionally start hammering again, but not for long, and it's back in the mild vibration mode. It's totally useless for the hammer function now (which was what I bought it for), and I've gotten only about two hours worth of use out of it. I'll return it tomorrow, and I'll probably upgrade to the next model up in hopes that it lasts a bit longer.
