This little monster might not have enough power for lots of heavy drilling, but it has more than enough to make you very, very sorry if you are foolish enough (as I was) to forget to unplug it before you change a bit. It took off at full speed, the cord wrapped around the paddle trigger, preventing it from turning off, and the whole mess jerked from my grasp and wrapped itself around my left hand. When I was finally able to unplug it, I was amazed to find that my first two fingers were only badly bruised and not broken. I would have said that what it managed to do to me was impossible. Wrong. Painfully wrong.Look how close the paddle is to the chuck. It's practically impossible to change a bit without depressing the paddle. If it's plugged in, you won't like what happens next.
