This is crap. Trust me, I spent a lot of time looking at toolboxes before I bought one. This does NOT have ball bearing slides; the drawers work fine until you load them up with weight, and then they feel awful.
Advice? Go to harbor freight. Look at the red thick metal model. Great box, great quality everywhere. This Craftsman one is just cheap lima beans with a craftsman badge stuck on it, if it didn't have that badge people would see it for the garbage that it is. Also, right after Xmas you can get this same size box at sear, WITH ball bearing slides and more features, for less money.
