Hard to reach sockets? We\'re really impressed with this pack of 3 remote control power sockets. Now you can switch the power on/off to any appliance from the comfort of your armchair. You won\'t need to leave appliances on standby ever again - saving both money and energy or have to twist or bend to reach awkward low-level sockets behind heavy furniture either. Our sockets plug into a standard 3-pin socket making them instantly controllable at the touch of a button from up to 30m (98ft) away. And because they work through walls and floors, why not switch on your lamps or electric blanket before going upstairs - bliss! Socket measures a compact D4.7cm x H10cm x W5.5cm (1.75in x 4in x 2.25in) the remote measures L8.2cm x W3.6cm x D1.5cm (3.25in x 1.5in x 0.5in). The remote requires 1x 12V 23a alkaline battery (not supplied).
