Connect your appliances into the Kill A Watt, and assess how efficient they are. A large LCD display counts consumption by the Kilowatt-hour just like utility companies. You can figure out your electrical expenses by the hour, day, week, month, even an entire year. Monitor the quality of your power by displaying Voltage, Line Frequency, and Power Factor

Worth the money!:
This is a very informative tool. We ordered two, one for ourselves and one for a gift. It is easy to use and will help us make decisions about how we use our electrical products. We expect to minimize our use of electricity and thus save money. Highly recommend.

Great features, but could use improvements:
This is a great little device with a lot of features for the price. I bought the device to see how much power my 40" LCD tv, amp, and PS3 were drawing. The only problem I have with this device is that the screen, despite the large size of the numbers, is difficult to read due to really low contrast. You have to view it from just the right angle, and usually with the aid of a flashlight. This is really hard to do when you have baseboard-mounted outlets like I have. I would be curious to know if... more info
