I bought this to work with my RC cars because I was tired of using hex screwdrivers by hand. Got a Milwaukee M12 1/4 hole punch but thought it would be too much for the 1.5/2.0mm hex head screws. At first I loved this tool, but then it dawned on me that I could assemble it by hand faster than this tool works. I guess it's not surprising considering it's only 4V, but I've since used hex drivers again and my M12 has at least some speed. There's nothing wrong with this tool, it's actually pretty good for what it is, just painfully slow. It's light, charges quickly, and seems to hold a charge for a while. I'd love it if you never used real tools, but I really don't recommend it.
