I can't believe how well this cutter cuts. I have to run it a bit slower, 520 ipm at 18,000 rpm, but it's worth it for the cut quality. I used to have to set the edgebander 1.5mm on the mil to get rid of chipped edges, but now I could skip the pre-mil altogether if I wanted to. I haven't had it long enough to see how long it lasts, nor am I sure I can send it in for sharpening. I have cut about 30 sheets of melamine so far and the cut quality is still fantastic.
