      Hang on to this, It may walk.

      Overall: 3 out of 5

      Kill-A-Watt monitor. The reason I bought another is that someone also liked my unit and it vanished about a year ago. I was lost without it. Imagine measuring a refrigerator, or freezer and knowing exactly what the power usage is so that the electric bill can be budgeted. I especially like the Volt-Amps and Power feature that takes into account the power factor of the load (phase difference between volage and current). A neat little device that I'm now hiding from others. PS. Can't seem to adjust stars for Value and/or Quality but my official feeling is that this deserves a 5 star rating for both.

      Kilowatt Meter

      Overall: 5 out of 5

      I ordered 2 of these meters and they work great! You will not be the least bit sorry if you order one of these Kilowatt meters.

      Great product but sparce instructions

      Overall: 4.5 out of 5

      This unit does what it claims to do, but there is very little in the way of instructions. While it's true you just plug your device into it and it into the power outlet, more information and suggestions on using it would be helpful. Suggestions on long-term analysis of products; things to watch or look out for, etc., would be least to those of us who are not certified electricians. But yes, it works as advertised and seems well built.

      Saved me a lot of money!

      Overall: 5 out of 5

      This is a great item. Very easy to use; just go around the house and plug things into it. You may be surprised at what electric items use for power (even in the off or standby mode). I found that I had an older freezer pulling an enormous amount of power compared to the newer models. Time to get rid of or replace the freezer. This is saving me much more than I spent on this item.
