here is the deal on the gator grips:
I have about every size socket ever made, but I still own one of these, because what they are good for is things there is no way to get a good grip on like rusty battery hold down wing nuts or broken plastic radiator petcocks, etc. - things where good knipex pliers might work fine, but there is no access.
so once you look at it that way, it is $10-$13 well spent!
