I like mine too, but it's more of a catch-all for stuff that's not quite EDC but that I'd like to have handy -- the CountyComm GP-5 radio, extra 2xAA flashlight, spare batteries, small tools, various items I like to have available on the front seat while driving. It's not an organizer, just a place to put stuff so it's easy to grab and go.

As an addition to my range bag it would be great for carrying additional ammo or stuff like eyes and ear protection if they don't fit in your range bag. I may get a second for that...

You can even drop a spare set of keys in there.
