Drive speed is too hard to control. It will break away from you, and if the angle and force of the pressure isn't perfect, it will turn on you, snapping the screw and chewing on the bit. At least in terms of the Phillips screw. He could use better variable speed control or a control switch that adjusts speed. For the drill I would give it a 5 so far, but for the driver I would give it a 3. Overall, though, I like the performance.
