Product Description:
Connect your appliances into the Kill A Watt and measure how efficient they are. LCD display counts consumption by the Kilowatt-hour just like utility companies.

Rating : - The EZ is much easier to use
I had the older Kill a Watt and it was really good but you still had to do the math to figure out costs. With this one you just program a rate and it will tell you what each appliance costs per day, week, month, or year. This is GREAT.
