This unit has so many flaws it's hard to know where to start: 1) It's designed to hold heavy tools on the bottom and heavy chargers/battery packs on top. The metal is very thin and I can bend it with two fingers. That will wear off quickly. I wouldn't use it to hold my car keys, wallet and phone let alone heavy tools. 2) There are four slots for different width tools. I have all the standard DeWalt and Milwaukee tools, nothing exotic, and because of the width chosen (about eight tools to choose from) I can only fit a drill in the receiving slot. The other three slots are empty because none of my tools fit in them. Who chose these latitudes? The slot width measurements shown in the images on the website are also inaccurate so you have no idea. Now it really annoys me that I have to waste time and energy to get it back. It's a damn good tool. Who would have thought that you could mess up your design so much and then have the audacity to charge $60 for a $5 device. Attention Emptor! For the price, I was expecting something to sit on once installed and that would see me through. Revain used to do a pretty good job removing junk from their site, but this and a few other recent cases say that's no longer the case!
