 it works and pretty accurate too. October 10, 2008
Larry G. (Auburn, ME)
The price is right on this little gadget. I agree with prior reviews saying a "backlight" would really help (Yeah, a flashlight is an option but where is it when you need it.).I tested mine with a 60 watt bulb, read 61 watts. Close enough.Found that my computer power factor (efficiency) is 74% contributing to dirty power, my new refrigerator power cost is $4.80 / month @ .16 per KWH.
Well worth it considering other meters are $78, $155, and $300 for a similar item.
Buy it, learn to use it, you'll like it.
As advertised, works well October 9, 2008
T. Bono (Arlington, VA)
I bought this product to charge my Electric vehicle and get an idea of how much electricity I'm using for a given trip. It works very well and I've not seen any problems as of yet. I did not go through the checking and calibration procedures as others have because I simply need an idea and am not selling KWH's. The instructions are very lame but with a little fumbling around in the basic menus it's real easy to figure out. I agree with several other postings that a back up battery would be nice to view data when it's unplugged but that would only add to the price. A cheap lamp extension cord at the bench could act as a data reader when not in use. Very nice little gadget. Buy one, you'll not regret it!
 Great product, but a few changes would make it excellent October 9, 2008

This product works just as advertised and I am really happy with the information it provides. There are a few easy modifications that would really make it much better. It needs to be back lighted. I have to use a flashlight to see it in most cases. It could also use a 3 foot cord so it would be easier to access. Also in today's world many places use timed rates and this does not account for that but overall it gave me the info I needed even if I had to provide light a little math to figure my cost on a timed basis.
Useful, but not perfect October 6, 2008

Very useful for determining the amount of energy used by major appliances. I like the fact that it keeps track of total energy consumption and uses the actual energy cost to forecast the cost of operation. This information is very useful when targeting appliances to reduce energy consumption. It is also useful for evaluating how successful I am at reducing energy consumption.
I don't like the fact that the LCD does not have a backlight, and that the display can only be read while the unit is plugged in. I have to get on the floor to read it. The unit also blocks both outlets.
I recommend getting a couple of extension cords and using this device "in line". Use one cord from the kill-a-watt to the wall, so that it's easier to read, then another cord from the kill-a-watt to your appliance (not needed if your appliance has a long enough cord).
 Useful, practical October 3, 2008

This Kill A Watt Monitor gives me the data which I was looking for. I use it to check my personal appliances and electronics. My use is simple and I have nothing to compare it to, so I give it a good rating. It could us a back light on the monitor for convenience.
