This is the perfect size to add extra plugs to your sockets. This leaves enough space to use an additional plug in a duplex socket. Four stars because it comes out of the wall when you unplug something (unless you're holding it while unplugging). I wouldn't recommend this for things you need to take off frequently like a computer charger or hair tools. But I will most likely buy more.
