+1 for avoiding the bigger name brand inexpensive tool boxes. I have dozens of older Craftsman tools, and had an older tool box that was solid as granite.
For Christmas I was gifted with the stackable 3 drawer sets from Craftsman... I had to return them twice.
The sliders of the first set came apart in the box. and the bottom (where the wheels mounted) was crumpled in shipping on the first one. On the second one the sliders came apart , and the fronts of the drawers were bent in.
Not very secure if someone trying to break into a locked toolbox can simply push the drawer in like tinfoil and reach past it. They can't even survive being transported to the store.
It was NOT fun having to drag my gift-giver out repeatedly to exchange, then to get the items refunded to their accounts, rather than turned into gift cards. Thankfully they were nearly as offended in the drop in Craftsman's quality as I was.
Maybe I'll have them spend the money on Snap-On gift certificates and save up the difference in price myself.
