I wish I had two of these last year when I started building an addition on my house. I bought one and quickly found I need two more (a second one for me and one for my wife!) I have spent years balancing tools on ladder rungs and holstering them in nylon bags. (Has anyone else wasted the battery when the trigger turns on while walking around or climbing a ladder?) I have Dewalt cordless tools and they clip in real well, but I did spread the opening about 1/8" to get them out a little easier. I have a 2" tool belt and the clip has never popped off on me.I have found my productivity has increased in the few precious hours I have to pursue my home improvement projects each week. My knees and arms don't get as tired from tucking power tools between and under them while I dig for another screw. No more fumble & bumble in my yard! Everyone ought to have one for each hip.
