Great idea for those with a ceiling mounted Infocus 4805 annoyed by the remote only putting the pj into standby and not shutting it off completely! I bought a pack of three remote controlled plug sockets from B&Q for £20!! The remote works via radio control, not infra-red so it will even work through walls, ceilings etc. You just plug one of these into your socket, plug your electrical unit into this device and hey presto, you can turn the power on and off at will. great for remote controlled lighting too. plug lamps into these and you can turn off and on the lights when your movie starts without having to keep getting up and down! Great idea and sensibly priced!
