Boy Howdy, does it multiply. I have mine all over the house, garage and shed. But, if you ask me where something is I can go right to it or at least the right vacinity.
I was serious about using the ceiling Beck, DH is building me a couple in the garage between the spaces for the car and above the fridge and freezer. It hangs down from 2x4's and has a piece of plywood that goes in between for the shelf. It high enough I don't hit my head and a small stepstool is all I need to reach the middle of it.
