Extreme Tools PWSRC4129TXBK Deluxe Extreme Portable Workstation and 11-Drawer 24-Inch Deep Roller Cabinet with Ball Bearing Slides, 41-Inch, Black

So far so good. I bought this (the whole upper and lower unit) about 6 months ago I think. I haven't rolled it around much yet, but i already have a lot of tools in it (just about all the tools I own). I love the organization of it. I bought this box specifically because this is the only toolbox I've seen with the slanted upper and that's exactly what i wanted. Montezuma has one too, but I honestly think this is the Montezuma just rebranded. I don't have the ridiculous amount of money for Mac, Matco or Snap-On, but this one seems pretty well built. I read reviews on it before purchasing it and one person said they were rolling and it wasn't nearly loaded to the capacity it says it can hold and the caster/wheel bashed in a bit on the bottom and now it's at a bad lean. Because I read that, I still ordered the tool box but I bought some 1/4" thick cold rolled steel plate (4" wide) and cut two pieces to the length of the width of the box itself. I drilled holes in the plates so the caster bolts could go through and mounted these two plates wide-ways between the casters and the bottom of the box. I really feel like this buckling issue the other guy experienced will not happen to me, lol. Otherwise this seems like it will continue to be a very nice toolbox. The drawers slide well on the bearings and I like the autolocking feature of each individual drawer. You just lift the handle as you pull the drawer out, and when you close it, you hear it latch again.
