Worked great until accidentally broke in the middle of a cut on the first project I used. I used all of Amana's recommendations for settings and just cut MDF. Unfortunately, Amana didn't help either. They contacted me and asked me to send them all the details of the project and I haven't had a reply from them since, which was a few weeks ago, but I think it's because they left themselves on their website , as they say they can." t guaranteed against breakage on their smaller bits.
