Review title: Easy to use, but wish it could save data
Product review: The Kill A Watt is a great little gadget and makes a great gift for dads. Just plug it into the wall and plug your appliance into the Kill A Watt. Within hours, days, or even weeks, you can calculate how much that appliance is costing you. My only complaint about the product is the absence of a battery, which means it loses all data as soon as you unplug it. Be sure to plug it in where you can read the display.
