I use this with a Malco TS1 as shown in the picture and a DeWalt 20v cordless drill Installation went pretty smoothly...once I figured it out! There aren't any valuable instructions in the box, but it's not that difficult. There is a rear screw that you hand tighten and a front screw that you use to replace the existing screw in the scissors. The clamp is very light, so the tool does not become heavier. The only downside I found was that it blocks access to the drill's speed and torque controls. But I got around this by adjusting the settings before installing the clamp.
