Mitsubishi Jet Towel Dryer, provided by Keren David. She said: "These futuristic sleek white dryers seemed strangely out of place in the stable-door style toilets of the National Trust property at Stourhead, Wiltshire. Sticking your hands in the blue light was amazing - a powerful jet of warm air dried them almost immediately. No other hand dryer I've experienced has come near to their speed and efficiency. And the National Trust has a huge poster explaining how to use them, with a helpful diagram, which shows it has low expectations of its visitors' IQ."
