What you need to know: DIY Kyoto Wattson 01
We like:
The glowing light showing electricity use; the tilt sensor; offloading the electricity history to our PC; the ease of use
We don't like:
The price; the short battery life; the very buggy PC and Mac software
SmartPlanet judgement:
Buying a real-time electricity display like this one could save you between three and 15 per cent on your bill. And although the Watton's steep £150 price tag means you'll need a while to make your cash back, we think it's worth every penny. It's a talking point for visitors, a reminder to housemates and family, easy to use and blessed with a unique peer-beating ability to offload your energy history to a Mac or PC. The short battery life and buggy software annoy us, but the fact it's made in Britain and is incredibly handsome ultimately win us over.
