I love this thing. I totally nerd out with it. I have power consumption spreadsheets for most my appliances now...and their different settings. I test my 1/2HP aircon on all different settings. I tested my fans (high, medium, low), tv, laptop, etc ...basically anything I can think of that seems to be a power drain. I tested it in the USA on a ~110V/60Hz outlet, but mostly I use it in Asia where the outlets are 220V-240V/60Hz. I cringed the first time I plugged it into a 220V outlet, but no issues, funny smells or smoke. It seems to be pretty accurate as my apartment meter has a digital readout that shows my current usage (but, I have to subtract the difference... total(on) minus total(off)...and be aware if the refrigerator compressor kicks on or the like). I mostly use it for define wattage and sometimes voltage, but it has several other settings that seem to work as well if I bothered to use them. Anyway, 6 months and all's well.

Awesome Monitor

This is a great monitor. Breaks down wattage usage in hour, day, month and year. As in other reviews it's just an awesome monitor and other reviews has it not so awesome as it may overheat and melt even under the rated wattage. Not that expensive for what it does. If any improvement would be to design the lower half plug in area so that the lower plug in your house receptacle can be used. Right now the monitor takes up the space of a duplex receptacle. You will need a power strip of some type if you have other appliances or lights plugged in. I watched a 9 minute video someone had made and it convinced me to purchase this one. Glad I did. It's being used to determine how many times in an hour or day our sump pump cuts on and off. I have an alarm on the pump when it doesn't not work, but I am interested in knowing how often it cuts on and off, during rainy days. I can figure this out from the wattage usage. I'm done typing. Just buy it and put it to use.

Saved me some serious cash on electric bills...

The Kill a watt EZ is everything I'd hoped it would be. We moved into a new home, and have to use the existing older fridge until we get the money saved up for a new one. I was worried that the older fridge would end up costing us an arm and a leg in electricity costs, as well as some other appliances in the house. My brother suggested the Kill a watt EZ, and it's awesome! I found out that our fridge, at least for now, is alright to use until we can afford a new one, as well as which appliances to use, and which one's to avoid prolonged use. You can plug it into an outlet, hit the reset button, and then remove it again, and it's ready to test your fridge, in it's hard to reach plug in. For best results, leave it plugged in for like 2 weeks to get a really good average, and then just remove the meter and plug it into an easier accessible plug in to read the results. ( in other words you don't have to pull out the entire fridge to read the meter) Anytime you have a questionable appliance or light or whatever, just plug it into the kill a watt EZ and you'll know if it's energy safe, or a power hog.

Works great - very handy device for tracking down excess electric usage

After having a spike in my electric bill, and no idea where the usage was coming from, I bought this device in hopes of tracking down the culprit. And it works. Just plug your appliance/device into the front plug, plug the Kill A Watt device into the wall socket, and after 24 hours you will know exactly how many KWh that device is pulling. I was amazed. Obviously it is only 110/120 volt and cannot be used on 220 volt appliances like clothes dryers, ovens, etc, but this will still allow you to track usage down to perhaps one of those appliances by eliminating others. In my case the 110 volt refrigerator was the issue and a service call eliminated the issue.

Great for the price. Works well and easy to use.

Seems accurate and is very simple to use. I love being able to know what the true power consumption of my devices are. I have two gripes for future generations of this product ... 1. I wish it had a light up LCD that activated when you pushed a button. It's really hard to see the screen, especially when it is plugged into a low, dark outlet. 2. I wish the plug on the back was rotated 180 degrees so that the unit went DOWN from where it was plugged into the wall, instead of UP. It is next to impossible to use this thing in conjunction with a power strip.

Love this thing

Love this thing, great for figuring out how much power different things draw both instantly and over time. I also bought a 3 ft 14 awg extension cord to go with it, to make it easier to look at while in use and to not take up both plugs on the wall socket. Works great. I've used it to measure my computer station, just plugged the power strip surge protector into the kill a watt and could see the immediate difference in power wattage draw when I turned on my monitors. Left it plugged in for 24 hours to see how much KWH it uses in 24 hours. Will leave it on for longer later, but for now, moving on to the fridge. Then the TV entertainment wall, and on and on. Great for planning solar installations or just to see how much each appliance is costing you. Love the fact that it retains its memory even with a power failure. Great if you're trying to measure an appliance's power draw over a month or more, and then the electricity goes out for a minute and you're not starting over. I think another model doesn't do this.

It's good to know what things cost.

Does what it says. I was a little frustrated with the cost of this item. I would have liked to log metrics on my devices, but it is some major $$$ to get data logging. That said, I found I didn't realy need to log everything. I just plug it in, reset the use meter, and let it run on a device for a month. Then I get a good idea of what my file server, mini fridge, etc. is costing me a month. You can enter your utility rate and it will calculate the rest. It doesn't loose the utility rate on reset, which is nice. I got this because I was trying to determine if the old Dell PowerEdge I have running in the garage was costing me more than a Digital Ocean droplet would have. It turns out that it is costing me about $25/month to run the thing, but a similarly sized droplet would be crazy expensive. So the old beast stays around for another year.

Nice multi-screen power meter for both power consumption awareness and general power information.

Nice multi-screen power meter for both power consumption awareness and general power information. I frequently use it for seeing how much power a device actually uses compared to its label as well as its power factor. Good for long-term cost calculations as well once you input the power cost in KWhrs and leave the appliance running for about a week. Don't expect to be able to pump more than about 1400w through it constantly though, it can get concerningly hot if you do that (as with any USA 15A outlet don't put more than about 70-75% of the rating through it constantly).

This tool saved me thousands. Fascinating education about your actual power use

This thing was fascinating to me. It was very easy to use. The main reason I liked it was because I got to learn about different appliances in my house and sort of debunk myths about them. I always thought my battery charger for my drill would be a real power suck -- nope it was $4 bucks a year! This little gem helped me to learn about power consumption in my home. After I had plugged it into a bunch of appliances, I came to the conclusion that 98% of my power was being consumed by my pool heater and air conditioner fan. The little appliances didn't really matter in the big picture. I would recommend getting one and playing around with it. You will save yourself years of guilt for leaving that light bulb on, and come to the realization that your power consumption is probably coming from 1 or 2 big things in your home.

Great, but it is a shame it does not have an LED for display lighting

Bought two of these and they work great. I went around the house and got all the power requirements that everything needs and gave me some ideas on how to save power. The only problem is that there should have been a small LED for the display. It is almost impossible to read it and I had toi crawl on the floor for most of them. it did not take long for me to get out my cord extension which made it a lot easier to work with.
