So I've used this tool a lot in the last few days, and it's awesome! One big bonus that I hadn't even thought of is as a sheetrock saw. I had to cut out a large portion of a wall, to insulate for sound deadening, and the semi round blade cut through the sheetrock like butter. It was easy to follow my guide lines, and very little dust to clean up. Was great for cutting out around switches and power outlets too. It also has worked great for cutting back base trim in place, cutting off the excess of door shims, and even cutting through 1/2" plywood.
I see a lot of uses for this little tool. Finally, something at Harbor Freight that I can hardily recommend!
