Key loss, like memory loss and for some, hair loss, is one of life's inevitable occurrences. Fortunately, unlike the latter two, there is a cure, and here it is. This great gizmo understands that unlike key-finders of the past, you are bound to have more than one set of keys, and so can locate up to three different sets at the click of a button. Whether it's your car keys, house keys, garage keys, whatever, simply press the coloured button corresponding to the set that's gone walkabout, and they will beep at you until you locate them. Normally in your other jacket, deep in your handbag, under the sofa, or if you have children, possibly in the fridge. Who'd have thought that someone would come up with an idea that almost makes losing your keys fun!
