This is the kind of tool that ends up within arms reach almost regardless of what I'm up to. Fits to my hand like it was custom made for me. Powerful for something so small. Battery seems to last forever, and charges in a very short time.If I had lots of screws to drive, I'd use a full size drill with a higher top speed and even more power because that's what they're designed to do. The Bosch Pocket Driver is the convenient, gutsy drill/driver that you can stuff into your pocket and take with you wherever you're headed. Fabulous tool.
