After unscrewing the drain plug screw, I thought I was about to be screwed because there was absolutely nothing I could use to remove the suction cup. Buying this product was my last resort before taking the car to the mechanic. The original plug size was 12mm and after eating it so hard I had to use 10mm of it. After I knocked the shit out, it finally got a grip enough for me to get the damn thing off. A mechanic will typically charge at least $50-$60 to remove such a broken nut. But by spending about $20 on it, I saved at least $30 there, plus a lot more the next time something like this happens. Buy this if you work on your own shit, THIS IS A MUST HAVE FOR ANY MECHANIC! A GOOD THING
