 Amazing Mar 09, 2010
First off, I purchased this from Radio Shack and not Amazon for about $24.99 plus tax.
The knowledge this product will save me $158.40 a year based on $0.12 a kWh just on what I learned about my computer. My computer's surge protector used .11 kWh in 44 minutes in stand by mode. That's about 110 kWh in a month or about $13.20 a month. I mean come on!
I have had my computer on stand by mode for at least 9 years! That is $1425!!!! Having a tool like this is amazing and incredibly money saving. If you don't buy this, you are wasting your money. Having my HP Laptop charger plugged in but not connected to the laptop, used 0 kWh. Right now I am checking to see how much it takes to charge it from 0% to 100%. Then how much it uses to leave it connected 24/7. I am having a lot of fun with this. BUY IT YOU WILL LOVE IT!

Alot of info for a small price Mar 05, 2010
This unit works great, it will let you know how much energy you are using when the unit is off, or working at full load. I worked in the electronic industry for 36 years, this unit is as good as some of the voltage analyzers I worked with that cost a thousand dollars!
Just plug it in Feb 28, 2010
Fantastic device. The first appliance I tested was my 30 year old Amana 13 cubic foot upright deep freeze. After three days it had used only three KWH. Convinced me there was no need to spend a lot of money to replace it while trying to reduce operating cost. It's on loan to a friend right now and he's thinking of buying one for himself. When I get mine back I'll be checking everything that's plugged in.

Best Money I have spent on Amazon Feb 26, 2010
I am just so pleased with this Kill A Watt unit. It has been fun to use and and investigate all my power consumption. Some things are just for infomational purposes because I can't unplug them(i.e. Refridgerator) and others are devices where we can change our habits some and start savinfg some real money every month.
Pros: Easy to use, inexpensive, small profile,
Cons: Setting disapear when unplugged, zero directions
I think that the company that made this unit could be more helpful if they were to offer a spreadsheet on their website that people could download and use for figuring out their power consumption. I made one myself but it took a lot of time. Also not everyone is good at math and formulas it would be helpful if they offered a small cheat sheet for people to use to help them get started on the math of KWH and how we are all bileed for our electricity.

P4400 Kill A Watt Feb 26, 2010
I wanted to put a Microsoft MCE computer on line in the living room, but I was afraid of the power usage, We live in Hawaii and pay some of the steepest prices for electricity. Using the P4400 Kill A Watt put my mind at ease. The LCD screen is very easy to read, I had no issues or problems with operating the device. Its nice knowing just how much electricity a device will use, and estimating how much it would cost to run, helps. I'm glad I bought it and would recommend it to anyone.
