i had bought a craftsman one, and it about stripped out my drain plug. it never clicked. i was pretty heated about it, so i opted for something a bit nicer.
i vote for grips, they made a world of difference also, a good set of gloves and loosen up on the bike man. i used to hold on so tight, it would hurt my hands and wrists. loosen up, let the bike do it's own thing, you'll be a lot more comfortable.
