Rated 4.0 out of 5.0 by Kromehog Functional device
Open the package, plug it in and go! Operation is fairly straight forward and readout is large and clear. Quality seems excellent. Unit is large enough that whatever dual outlet you plug into, the second plug is blocked. This also means a combination plug/switch is not available. Back-lit screen would improve readability.

Rated 5.0 out of 5.0 by blrow3 Great way to kill those energy vampires in your home!
The kill-a-watt Es power monitor is super easy to use and understand. It gives you real time data on the power consumption of whatever device you plug into it. This unit had helped me identify several electronic devices and appliances that I thought were in a low-power or off mode, but we're wasting a ton of electricity! This u it paid for itself in the first month! Great addition to my toolbox!

Rated 5.0 out of 5.0 by Jornie1 Excellent Product....Great Price
This meter is exactly what I needed and the price/value was excellent. It does precisely what I had wanted. Accurate line voltage to a given appliance while at the same time giving me wattage, amps and cost per day, week or month for that appliance based on my cost per KW charge by my electric company. Great product.

Rated 5.0 out of 5.0 by SteveVA Very handy for your budget and generator
I enjoy using this device around the house since I have received it. The manual is easy to follow and I quickly set my rate to 11 cents per kWh, which is what I pay. Once the device is plugged in, you get a reading quickly. It averages out as the device (like a fridge) runs then stops. You can easily scroll through the hourly, daily, monthly and yearly costs. If I charged my phone continuously for a year, it would cost $6.57 as seen in the photo.
Other readings include Hz, watts and amps. All are important if you use a generator. I have a 2000 watt generator and can tell what my appliances, such as my fridge, draw so I know what I can plug in. Hz is important as well for sensitive electronics such as phones and laptops. My outlets and inverter generator read around 60 hz, where it should be.
I plan to get a lot of use out of this device and recommend it if you are curious about cost, especially and extra fridge or TV. One downside is that the device is a little big so it won't fit well on a power strip.

Rated 5.0 out of 5.0 by Robg Puzzling at first, but just took some practice
The P3 EZ meter was a great buy. It took me time to learn how it worked, but after watching 2 YouTube videos where people showed how it worked I was able to get it working well. Would definitely recommend this thing for anyone trying to identify an energy hog.

Rated 5.0 out of 5.0 by Chris Great for measuring PC power usage from the wall...
I bought this to be able to measure PC hardware power usage and it does that very well.

This really works well. I was trying to determine the start up wattage of a freezer so I could decide what generator to use. Worked as described.

Rated 1.0 out of 5.0 by Saber unsure of true usefulness
Sorry to say, but the device isn't that user friendly... I tried it out initially with my 10 year old refrigerator. per the instructions, I had to find my electric bill in order to program it properly. After about 5 - 10 minutes, and hoping that I had it set up right, I unplugged my refrigerator and tried to plug it into the meter. I had to put a considerable amount of force on the plug to get it in it. In order to get an accurate measurement, I had to keep it plugged in for a couple days, due to how the refrigerator ran. When I attempted to unplug the meter from my refrigerator, I was concerned about the the extra force on the plug applied to get it out of the meter. It is currently sitting unused in my garage.
