It holds so many plugs!
Size: 6.5 Ft, Color: Black
I am using this to plug all of my Christmas village pieces in. I haven't used it yet, but it's going to be great to keep the plugs all in one area.

well designed
I have two of these. The number and orientation of outlets has fit all my needs. I haven't needed the USB's yet, but I'm glad they are there. The thin plug and off-center angle are very useful. One is in use under my three seat power reclining sofa, guitar multi-effects, and a couple lamps are plugged into it. The other is in a drawer powering the air pump, power filter, lighted hood and heater for the aquarium on top of the dresser it is in.
