The Intelliplug is easy to use, saves energy (and money and carbon emissions) and is a great, simple product for the house. It reduces standby power usage in a very convenient way. You choose a "master appliance" (PC), plug this into the Intelliplug's master socket, then plug other appliances that are used with the PC into the peripheral sockets (monitor, speakers, printer etc). When the PC is switched on, power is given to all the peripherals at the same time. When the PC is switched off, power is cut (after a short delay) to everything, and nothing is left on standby. You also get surge protection for all appliances plugged into the Intelliplug.

The intelliplug itself consumes around 0.5 W, which is much less than the standby power typically used by PCs, monitors, printers etc. Standby usage for a group of PC appliances should be cut by at least 90%.
