Find these really useful for killing power to things like home cinema set ups, hard to reach sockets or the like. Just plug it in between the plug you want to control and the socket, and you're pretty much away. Range is pretty good in my experience (through internal brick walls), you can have three different groups controlled from the one remote, and there's four different remote groups.

The new socket from SMJ combines a simple ''plug and play'' operation with the ability to save money and energy. It is simple to use and operate and when used with an extension lead you can control up to ten sockets. Its energy-saving attributes means you can turn electrical appliances on and off with the push of a button. Research shows that by turning off a TV/DVD/video/satellite box when not in use can save money over 30 a year in some cases. The tiny energy consumption of the socket when in operation also means that you are helping the environment. Many 100,000 tons of CO2 are wasted by household appliances being left in standby mode. Of course its not just TVs that can be controlled. Any household appliances, such as lights, stereos, radios etc can be turned on and off using this remote socket. To operate, set the dial on the reverse of the product to the channel required and fit the small battery to the transmitter. Plug the socket in to the required wall outlet and it''s ready to use. An additional three sockets per channel can be added and operated by the one remote control (Order code: N33GF for spare socket - please note that this is not supplied with a remote control). Note: Some manufacturers'' equipment may occasionally need to be left on standby to operate correctly - e.g. to record. Please check your manufacturers'' instructions.
