All this talk about the Craftsman Max Axxes set got my interest, so I went out and bought one - I got the 51-piece set because it was in stock (last one they had at the store) and the 80-piece set is catalog order only.
Very impressed with the ratchets, they are designed like the 'think profile' ratcheted they introduced a few years back. The sockets are if the 'flank drive' design.
The case, while nice and sturdy and has catches that snap close with a positive feel, is a total waste of space, it's way too large for the quantity it holds... this whole set will easily fit in a space about 1/2 of it, maybe even a little less.
I was a little surprised that the sockets are only stamped with the size and weren't laser etched like the rest of the current Craftsman sockets are, hell, even the 3/4" drive stuff is now laser etched!
In comparison I also have the Kobalt pass-through sets and they are laser etched and is the only marking on them, which is unfortunate because it's hard to read as the size of the text is way too small and the laser etching isn't quite as crisp and clean as it could be.
Overall, I'm quite pleased with this set. I didn't know Craftsman offered their own 'pass-through' design untl I read this thread. By the way, the sockets and extensions between the various Craftsman, Kobalt and Gearwrench brands are all interchangeable.
A couple of things I would like to see in this pass-through design are; 1) a universal joint... yeah, I know this would negate the pass-through design, but sometimes a universal joint is the only way to get at a particular bolt, 2) longer extensions, 3) 12-point sockets, and 4) a breaker bar, so that I don't feel that I'm putting too much stress on the ratcheting mechanism.
