I have owned a montezuma tool box for about 15 years. Great toolbox that I have mounted on a flatbed that stays on the farm. I needed a better box for my work truck so I decided to go with the ME300B. So far I like the box, not sure I like the new latch system and the gas strut to hold the lid up but I’m sure it will be fine. My older tool box seems to be set up better with the spacing between pegs for sockets and wrenches. The new one is a little tight when you get up to the larger end. I do like the deep compartments for odd tools in the center and the large storage for hammers and pry bars.
