I didn't really know what to expect but I'm very happy with my purchase! I've experimented with this, adjusting depth and using attack, and I'm very happy. I also had to try the power plug and liked the ability to hide my screws. I am about to make my first trellis for my father's mother's rose bush and this will make the job much better, maybe even more professional. It's also nice to know that I can purchase additional bits if needed! Good WL Fuller product, glad I did a little research!
