This little rough tool has enough power for tough drilling jobs, plus plenty of torque settings (and two speed settings) so you can finish/finish the job without loosening screws or over-tightening dives. I've drilled or hammered everything from concrete to kitchen cabinet fasteners and it's all done well. I get about 4 hours of moderate use from a full charge, and the included quick charger has the other battery ready when you need it. LED light is amazingly efficient. The light weight really helps reduce hand fatigue, especially when drilling at shoulder height and above. The compact size is really handy for drilling in those hard-to-reach places, but don't let the small size put you off. This thing has comparable power to my 18 volt and now I use it for my drill.
