Wandering about my local B&Q today - looking for a 2 gang to 3 gang socket converter (which I later found at TLC for 60% less) I came across;
Byron Remote Control Sockets.
Basically three adaptors that plug into socket outlets and a remote control. You plug your appliance into the adaptor. Then you can turn those appliances (up to 3000w) on/off via remote!
We have two table lamps and a floor lamp in our lounge, all of which are a PITA to switch on/off. No I can sit there & pretend I'm Ernst Starvro Blofeld! Great fun & useful for £20!
