The camping toaster is the ultimate WTF. Of course, we know what it’s for – we’re not idiots, the clue is in the name – but actually making it work is a completely different matter. If your idea of a hearty breakfast is a couple of slices of floppy, anaemic, slightly warm bread, then buy one now. But otherwise, forget it. In fact, forget it anyway. Save your £4 and buy a couple of 40w halogen bulbs instead.
