Our pantry doesn't have a built in light so I installed a strip light which plugs into the only single socket in there. This is also where we keep the Microwave, so each time I wanted the light I had to unplug the Microwave and plug in the light. When my Wife wanted the Microwave she had to do the same, in reverse. I knew what I wanted, so fix this problem, but couldn't find it. I wanted and extension cable with 2 switched sockets on it, but couldn't find one, or it would escape my mind to look for one, once out shopping. I then saw this and it's is better than I had thought I would get, no trailing cable to contend with. Now instead of all the unplugging and re-plugging, it's a simple switch for each plug. It's a great and very simple concept and we love it.
