I have the smaller Worx driver that has a revolver style bit cartridge.
I'd never have bought that on my own, but my wife bought one first and I liked it.
NOT a substitute for a battery drill, but great for light screw work and will drill with ahex shank bit in a pinch.
I also have a Work convertible 14" chain saw/pole saw and that is a tough little SOB.
Cut down two 50 ft tall 14" tress and the dual stump with it and nothing else (besides my truck for the stump pulling). It can also be upgraded to a 16" bar.
