It does what it's supposed to do very efficiently, and that's what I require.
I gave it 5 stars because it's the "old" Craftsman from Sears-not the new junk they sell that comes from China. The only issue I have, and it's very minor, it that the bits are too big for what I need a hand impact driver for. I have a few smaller-sized screws - @ 1/4" slots on the screws and a 1/2" bit is the smallest in this set. I did use the 1/2" bit on larger screws and it worked very satisfactorily.
