I use this tool daily in my service area to get into tight spots, it also works good on the end of a screwdriver, too. I was turned onto this by a guy I used to work with, I've had my current one since 2003, and the only thing thats happend to it is the little end of the drive shaft has broke off, but it is still functional and very handy.
Just found out that the new one I got is magnetic too. Thats pretty awesome.
