Sometimes a simple yet elegant idea comes along that solves a pressing problem, and here's a perfect example of that: 360 Electrical's Plug and Turn, a two-plug wall outlet that can rotate in any direction and maintain power even while being rotated. Each receptacle has 18 click stops around the full 360 rotation, giving you room to plug in bulky wall warts or oversized plugs with ease. It fits into a standard-sized electrical box, and has a nice-looking snap-on screwless wallplate.
360 Electrical plans a family of products based on this great idea including GFCI outlets, 20-amp commercial-grade outlets, 250-volt outlets, multiple outlets and even power strips. Wonder why nobody thought of this before?
