We've worn out our Snap-On impact sockets quite a bit lately, espcially the 15mm, it's most used in transmission removal. Crapsman, Snap-On, I see little quality difference, however, if I call my Snap-On guy at 1:00 a. m. with a BIG problem, he will come through for me, every time. That alone is worth the extra cost in tools. Also, SOME of their tools are definitely stronger and better. The cost sucks, but he has to make a living, and I don't begrudge him that, he has cut me more deals than I deserve.
