Wattson, by DIY Kyoto.
One of the better energy monitors on the market (and looks very nice too. The others you'd tend to leave in the kitchen and forget about it, the Wattson I have sitting beside the TV).

Children and wife now more aware of leaving lights on and wasting electricity. I believe it's actually saved me about £20 - £25 last quarter alone in electricity with everyone in the house being more aware.

I was looking at this last year, but it was a whopping £150 at the time. Bought it a few months ago when the price came down to £89 on Amazon.

Manufacturer emailed me with their special offer " a limited discount offer when purchasing a wattson. To take advantage of this offer, simply enter the promotional code: "A42XRENEWABLE" during checkout to receive a staggering £20 discount."

Save some money, save some energy, save the environment.
