I won't even say it. I just thought I'd say I just got a set of these things, and on anything except the most accessible bolt, they suck. They mainly grab with a small point(easy to strip bolts), and they only turn the bolt after more than 1/4 revolution on the handle (hard to explain, but really annoying)
just thought I'd tell, ans see if anyone else has had a bad experience with these things.

 

oh man I hate them............
