This wind-up gadget's a great way to kill two birds with one, remote control-shaped stone. As well as being able to learn the remote controls of up to six DVD players, digiboxes and consoles - enough for the most ardent home cinema fan - the Clone RC 601 is charged by wind-up power. So you can put away those old remotes and the half dozen battery chargers lying around the living room.The only potential catch is that the manufacturer doesn't say how long it takes to crank, meaning you could end up with more exercise than getting off your rear-end to change channels. We'll let you know once we've had a sample to test. In the meantime, you can buy one now for £20 here.
