Review on Upgrade your Power Tool: Black & Decker 5140112-17 Switch Kit Unleashed! by Victor Anderson

I would give a five star rating if it came with all the screws holding it together but it doesn't. The plastic knob, switch and included screws were top notch. If you count the handle, then there are more holes than screws. The screws, which were only included for mounting the handle and fastening the switch, with large threads almost like wood. The screws not included were thin head screws of various lengths that attach the handle to the metal body of the saw. They got rusty on my saw and it was very difficult to get them out without screwing up knowing I needed them again. They would be hard to find even at a hardware store as they need to be made of strong metal for high torque in a small size. I haven't seen a single kit with these torx screws anywhere. Oh, all the screws on my saw are torx. Installing the switch wasn't difficult, as was assembly.
