I previously had a 9.6v from B&D but the battery finally died. When pricing a replacement I decided to go with this one. What I like is that it fits in the solid plastic case I already had that came with the 9.6v one. for the price you'd figure it would come with drill bits but that's not a major thing.
The battery charge button tells you exactly where you stand and won't leave you up a creek when you need it most.
The only reason it gets 4 stars instead of 5 is because it doesn't come with it's own case or bits. I like all in one packs and for the price B&D could afford to include these things.
