I was quite skeptical about the quality of the finished work. Miracle. A tip before cutting, pasting sticky paper to paint finish on your board sided, spend it with the handle of a chisel or other, then cut the VERSO side you will have a perfect cut that also in major DIY. I have complete finishes with adhesive tape from the color of my kitchen doors. They are perfect and not see the difference. Never have I had such results before. Very easy to use tool. The clips on the stop can be set in either direction. Only a sensible allows it to be set well in the other sense it moves. Pay attention before you start cutting.
