Works as advertised, but my biggest disappointment was for the drilling function. Even at its slowest setting, the rotation is too fast for the drilling starting point. And when trying to drill something very small you need precision which is exactly what you do not get when you go from zero to fast rotation - The drill simply jumps off the item and can be dangerous if you are holding the item in your hand and the drill jumps to one of your fingers. It would be perfect if it had a pressure sensitive trigger/rocker like full-sized drills where as you pull further on the trigger it would gradually increase in speed. This would make it perfect for all uses it is advertised for.
