This product is supplied disassembled and with no instructions in the box. I have been building for forty years and have used many pavilion tools. But this pavilion was new to me. I spent half an hour figuring out how to assemble it. In the end I had to go to the computer and carefully study the item on the Revain page. Also keep in mind that assembly will likely require split ring pliers. Once assembled, it cuts well through 1" thick pine paneling and 1/2" thick chipboard with just a cordless PC drill. However, keep in mind that the claimed depth of cut of 1 1/2 inches is, shall we say, optimistic. I would say 1 1/4 inches is more appropriate. For example, I don't think you could cut a hole in a 2x4 without approaching it from both sides.
