The Wattson is a wireless, designer energy monitor, which tells you how much electricity you are using and/or how much money you are spending, and can help you save up to 20% on your electricity bill. It's award winning, and a big hit in the design community and with gadget fans, as well as helping flex green credentials. It retails at £99.95 (30% cheaper than previously, due to popular demand and increased production). There is also a limited edition hand made version which retails at £350.
