For the most part, we live in a wireless world. But, when it comes to things like extension cords, we need a little help to keep it straight. Enter the Cordpro CP-100. This little donut deals with unruly cords by storing them neatly coiled inside: up to 100 feet of standard 16/3 extension cord. When you’re done with the project, simply roll it back up into the shell. Easy as that.
