This year, get all of the people on your gift list money. Well, it may not be cold hard cash, but the Kill-a-Watt is actually even better because it monitors how much energy appliances are using and alerts users as to which are worth leaving on and which should be turned off. They’ll save tons of loot on their electricity bills – which will hopefully be re-routed into buying you an awesome birthday gift!
