Excellent.! Easy to Read and Comes With a Backlight.
This electricity usage monitor is a useful tool! The large LCD display makes it easy to read, and the eight modes provide a good range of data, including wattage, voltage, kWh, and the total cost of electricity consumed. It's simple to plug in and operate, and the backlight is a great addition. I've found it beneficial for identifying power-hungry appliances and those on standby, as well as for understanding my energy consumption. It's a worthwhile purchase for anyone looking to reduce their electricity bill.

easy to use and very helpful
so far so good.... practical, friendly and very helpful to identify the "vilans" of my energy bills

Good for what I wanted
Seems to work OK, monitoring, calculating and accumulating several factors eg voltage, wattage, even cost. But in the absence of any user instructions itโs difficult to tell what some of them are and how to set them. If you just want to know how much power a particular device is using at the present time it seems to work. The display is clear, the design and the build quality good.

Easy to estimate the cost.
It was extremely good. Now I can estimate my expenses. Special when we are staying in sharing.

Works fine
Works fine, but it would be nice if there was an option to keep the device display on all the time without having to press a button every 10 minutes. Cant say how accurate it is, I believe its at least fairly accurate as devices I tested showed within the expected ranges.

Super way to see your actual wattage
I'm really impressed with this power watt meter. I needed to know how much wattage my brand new desktop computer was using but mainly on the start up and this power meter monitors and shows me that type of information. Here is what the unit will display, the time since connected, the total amount of wattage since connected, the current wall voltage with frequency, the current amperage being drawn plus the power factor, the lowest wattage reading, the highest wattage reading and the total cost for running item. In order for the last one to work, I must enter the price it costs me per kilowatt hour which I got off my hydro bill. I like that this unit has two different resets, a factory reset and a soft reset which will only remove the accumulated data like time since connected, low and high readings. The unit comes with two reset tools, these are for the factor reset but any small blunt object will work as a reset tool. The soft reset is done by pressing two buttons on the front panel at the same time. I also like that I can change how long the screen backlight stays on. If I want to see how much energy my PC uses for the month, then I can set the backlight to turn off quickly but if I'm doing readings every few minutes then I can leave the screen on longer. My options are 10 minutes, 1 hour, 4 hours, 8 hours and stay on always. Since my GPS device doesn't say when it is fully charged, I connect my GPS thru the power meter. When the power meter wattage starts to decrease then I know my GPS is almost charged. This power meter also came in very handy as it detected that I was using a USB A to C cable that didn't have the ability to pass more than 2.5 watts. When charging some items, their charge time went from 4 hours to 10 hours so now thanks to the power meter, I checked every USB cable and have rated the cables to their wattage level. Now, I can grab the right cable when charging a device. This power watt meter is outstanding and very useful.

Excellent right out of the box (even with weird UI); great value
I use an Emporia power meter ( https://www.amazon.com/dp/B08CJGPHL9 ) to monitor whole-home and per-circuit power usage, but this product really allows me to focus on a single device. The display is clear and easy to read, and the values if displays are just the ones that I want to see. The "Function" button lets you cycle through the different display modes (e.g., Power, Voltage, Amps), and works exactly as you'd expect. Some display modes have a counter feature, which is also very nice - a graph would have been a nice add-on, but perhaps one wouldn't expect it for the price, which I hasten to reiterate is very competitive. The unit is solidly-made, and has no trouble working with relatively heavy-current items, such as a 1500W kettle, shown in the pics. My only complaints about it are the directed to the user interface. They managed to find room enough to put four buttons on the front of the thing, but to clear/reset the counter display you have to push "Function" and "Up" simultaneously. I may be some sort of weirdo special case, but "Function" (mode selection) and Clear are the only operations I'll ever care about, having set up the small set of configuration options. I expect that I'll only use it once a month or so, and I'll never remember the mysterious chord to reset the counter. I expect I'll write the cheat code on the unit with a sharpie!
