In general, the fire works, but for my own purposes, I find myself really missing the speed control. while you press it, it immediately begins to turn at its maximum capacity, and while you are working on minute details, it can occasionally "pull" out of your hand. Not in the sense that it is extremely possible to turn it; in fact, you can't even keep it; rather, in the sense that you don't anticipate that it will turn swiftly without acceleration. Krch job - you will understand:)
