An excellent tool idea... no more fishing around in the depths of you toolbox for that odd, huge socket you paid a ridiculous amount of money for because your oil-drain plug uses a massive size, usually well beyond the size range of your standard socket set. More than one vehicle? I shouldn't even have to say it...

This thing covers 12 through 19mm sizes, and you'll never burn your fingers fishing a dropped socket from the basin of hot oil again. Definitely worth the cash.

Buy it Here. ( Actually, you can't buy it here, you've got to find a distributor, but it's about 35.00. )
