 works good if u understand it July 2, 2008
our electric company has raised our rate a penny per kilo watt hour. This dose not sound like much but if my TV uses 200 kw an hour then it cost me $2 to watch 2 hours!
This Kill-A-Watt reader is great for showing me where my power hogs are in the house.
The only problem I have with it is that it was a little hard to understand. I wish that the instructions were easier to read and understand what the numbers mean.
This reader showed me that my energy saving light bulbs still rack up a lot of power! and so dose my laptop which I was always told used a LOT less power then a desk top.
 Great tool June 30, 2008
Quick delivery. Great tool. Used daily to track energy usage by my Zenn Electric Vehicle. Displays Kilowatts used, current levels, and more. Also used to track usage by portable AC unit. Good to know how much electricity is being used.
 Does what it says but not the best design June 18, 2008

Yes, the product performs as advertised -- it'll display the amount of energy consumed in KW/hour, watts, volts, and amps. It just doesn't have a very thoughtful design. Some comments:
1. As depicted in another reviewer's photo, the unit is bulky and the top extends a bit high over the prongs -- as such, it monopolizes an entire standard dual outlet requiring the user to unplug something else (probably the lamp required to see the LCD screen).
2. The LCD screen is not backlit so crouching behind a dark appliance to get a reading is a hassle.
3. It'd be nice if the unit had supplemental battery power to save the readout until you plugged it into something else (even better would be some memory to store multiple readings). The device is passive so once you unplug a device from it, the information is lost.
4. It doesn't compute KW/hour immediately. This is a fairly simple calculation for a device like this to compute on the fly.
At a list price of $35, it should have at least some of the features listed above. As it stands, this is a primitive device in "attractive" plastic cladding.
great for understanding and managing you electricity use June 14, 2008
Works just like they said, plug it in between a power plug (on the wall or a power strip) and something that run on AC electricity... the display turn on and shows you how much power in being consumed, Volts, Watts, Amps, KWH plus more. I was surprised to find how much electricity items around the house were using (some items like cheap phone chargers chew up energy just being plugged into the wall even if they're not charging something)
Fun, fun, fun! June 11, 2008
If you are like me and fret over every wasted watt of energy, then this gadget is for you. It is very simple to use and seems fairly accurate. Mostly it is confirming what I suspected about most appliances like, how much power is that TV really using when it is on or off....
The only drawback to the design is that the unit will take take up both plug spaces in a normal duplex plug outlet. The body of the unit hangs down too low and interferes with the lower plug. I use the unit with an extension cord to get around the issue.
For about $20 you can't go wrong and it will repay for itself in savings that you will make by realizing what to cut back on. I highly recommend it.
