Product Description:
Kill A Watt can help you reduce your power bill. Kill A Watt will help find power-wasting appliances then you decide whether it is worth keeping them plugged in. For standard 115 VAC appliances only, 15 Amps maximum, 125 VAC maximum.

Works as advertised and at a great price. But here is a little tip I picked up that you can get the energy cost in seconds - and no need to wait for 1 hour for the Kilowatt per hour calculation.

Plug in any device then press to select the Watt readout. Take that number and go to [...]

Just plug in the wattage readout, enter how many hours it is on (just enter 1 to show how much per hour to operate) and the cost per Khw. This is normally right at the top of your monthly utility bill where the calculate your bill. Example, I am in Iowa and a KHw is .08034

It will amaze you when you see how much power your devices turned OFF are costing you. Examples from our house - a flat screen in our bedroom costs $10 per year turned off. Laptops, plugged in - but fully charged and completely turned off - 7 cents per day or $36 per year. New computer with screen / printer all in standby mode - $80 per year. And the biggest - I put a small dorm fridge in my office = $51 per year. For that price I can walk upstairs and grab a soda.

What is shocking (pun intended) - with just 5 things we checked in 15 minutes we have cut our electric usage by 12%!!

As the saying goes "You can not manage what you do not measure!".. Now there is no excuse!

Rating: - Almost exactly what I was looking for.
This item was exactly what I was looking for. The price was right and it does what it says it will. It tells you how much elec. an item is using and how much has been used since it was plugged in. The only 2 things that I would mention that might be a negative are that it shows 3 watts being used when the item is plugged in with nothing connected to it. I am guessing that is how much electric is needed to run the device. And the more annoying issue is that it looses the recorded data instantly when it is unplugged. Don't forget this one, it will bite you. I wish they would have at least put in a short term memory and a reset button. But, it is not really a issue if you remember to look before you unhook it. Over all, I have no problem giving it 5 stars.

Rating: - Nice item to review your electrical use
Overall, I was quite pleased with this item. Simple to use, just plug in the your electrical device and push the watt button and you can see how many watts it's consuming. I used it to see just what my TVs and computers were using when I turned them off. I find my cable box uses as much energy turned off as it does turned on!

While it does plug right into a wall socket, I found it more convenient to put it on a short extension cord.

Rating: - Useful, but
Does what it says it will and will help us understand our power usage. However, with the display set flat in the surface, it is hard to read when in use. Think that most wall plugs are down low, or at best, at counter level. In each case the viewer must bend to align their view with the display. A display tilted upward would be an improvement.

Rating: - P3 International P4400 Kill A Watt Monitor
This really does work, but the problem is that there is no easy way to put this in a plug if the plug is behind something. Obviously houses have things in them, so that is a little disappointing, but this does work well. I think that it helps in understanding which appliances and electronics are sucking out the most energy, but the problem is if you have a ton of surge protectors, then unplugging and plugging all your things is a hassle. I think there should be a surge protector Kill A Watt which and determine how much energy is being used by each socket.
