My wife bought me the damaged bolt & screw extraction kit one of the previous times on Woot. What I got was what was shown in the picture this time, more or less (7 sockets – with no choice of metric or SAE, though – and two packages of the Grabit #2 and #3). However, what was shown in the picture that time was a package that included the Grabit #1 and #4, too, I believe. It certainly showed one package with four bits.
Why did I need two packages of the same thing? (Sure, I suppose one could break, but it’s not like I’m constantly removing stripped screws.)
On the positive side, I already had occasion to remove a stripped screw, and it did work.
