I usually don't pay attention to the TV ads, but was by Lowes yesterday and picked up one of those human powered screw drivers that either ratchets or goes double speed if you hold the collar.
( it really does not ratchet, just goes in one direction if you don't hold the collar )

That thing is slicker than snot on a glass doorknob !!!

For $20, highly recommended.

 

I had never seen or heard of one until yesterday when I was at Lowes. I played with it a few minutes and decided against buying it. It was very tempting and I really liked that it can reverse motion (you tighten clockwise but it spins counter-clockwise).
