I especially like the extra long deep well socket design. The deep well sockets will NOT fit upright in most tool box drawers though due to their length. Lug nuts / motor mounts / sub frames - if you have the impact to turn them they will NOT let you down. I almost didn`t want to use them when I first got them. GP is all I buy.Frankly I don't know if they're tougher than Snap-on or the rest.
