Kill-A-Watt Electricity Monitor is rated 4.4 out of 5 by 69.
Rated 5 out of 5 by from Is it a tool or a toy? In preparing my house for a backup generator I had to track all of my circuits. Websites get confusing as to how much watts a average product uses. The Kill-O-Watt allowed me to record 1 minute usage of my electronic devices to provide actual usage both active and standby. It can also be used to help lower your electric bill by identifying the "vampires" or heavy users. As a toy you can leave it on any appliance for a week to see how much kWh that device used. It also provides loads of information that can be helpful in re-wiring a house. I love it and am glad to have bought it.

Rated 5 out of 5 by from Excellent Item for Saving Money This item does not require any tools or batteries. Just plug it in then plug and electric item into it. It will keep track of how long it has been plugged in and also record the electricity used. To reset it simply unplug it and plug it back in. We have used it on two refrigerators, a heated waterbed and all the other electronic devices in our home. Based on the changes we have made this item will pay for itself in about five weeks. This item also alerted us to a malfunction in an item that could potentially have caused a fire.

Rated 5 out of 5 by from Accurate power readings I purchased this device to check all my power draws on the stuff we all have plugged in around our houses. I was shocked to find out how much some of the stuff draws even when not running. This unit will show you if your power voltage and cycles is what it should be at your appliances. It also tells you the amperage and wattage draws of the equipment you plug into it. On items that are randomly switched on you can set it to meter the power usage over whatever time frame you let it hooked up thus giving you a more accurate analysis of the true consumption of that particular item. I found out through my checking that I use about $200 worth of electric per year on simple things that are normally sitting waiting to be used. An eye opener.

Rated 4 out of 5 by from A Smart Tool For basic appliance not over 900 watts great to have. Wish for one that goes up to 2.0 Kwatts. Otherwise 5 stars.

Rated 4 out of 5 by from Helpful Tool to Determine Usage I was so excited to try this monitor on my refrigerator to see electricity usage. The monitor displays many different items, volt, amp, watt, Hz & KWH. This is a good tool to use to see what items in our home use the most KWH. The only downside is this cannot be used with an electrical extension cord. What refrigerator plugs into a socket you can see? You have to view the readings while the monitor is plugged in. That makes it almost impossible to use for a refrigerator without pulling out the refrigerator and taking readings while the monitor is plugged in. There is no memory, so when unplugged, you lose the readings. This is a good idea, but really only useful on items where you can get your face to the plug to read the output.

Rated 5 out of 5 by from A great add on for power monitering The first time I saw this item was not at Home Depot... paid way more than it costs here. I really appreciate being able to see what the Hz frequency is on the power line and on my generator. I can tweek the throttle to set it closer to what it should be. The only thing I wish there was a model which was for 220-240 VAC and one that was good for 5.5 - 6.0 KW. That would cover most all loads found in a home or RV. A model with a led back light would be wonderful as well since it is usually dark when the generator is running. The third thing that would be nice is to have a short cord coming out of the bottom to plug into instead of head on.

Rated 5 out of 5 by from Nice kWhr meter, easy to use Easy to use, just plugged in an extension cord from the wall so I could put the unit on the top of the refrigerator, then plugged the refrigerator into the unit. I look a the energy used every few days and the elapsed time to easily predict monthly and yearly energy consumption. The old refrigerator isn't so bad after all. I calculated that it would take 9.6 years to break even if I purchased a $1,000 energy star rated refrigerator. I guess I'll hold onto the old refrigerator as long as it keeps consuming a fairly low amount of energy. The home depot pickup was also a breeze, just showed my ID, signed the paper and said thank you.

Rated 5 out of 5 by from Such a neat idea Honestly, I never knew how curious I could become about how my appliances use electricity until I gave this a try... One of the things I had been wondering around my home was with recent additions of two different aquariums, and noticing that each had around 4 or 5 things plugged into it, I was really concerned with the level of electricity they would use. This tool gives you several different ways to track and monitor usage and it is dead simple to use!!
