I like it, used it to test how much Wattage my PC consumes but also tried on other items to see how accurate it is. Is pretty close i would say.

5.0 out of 5 stars Easy to use power meter
Reviewed in the United States on July 5, 2023
Verified Purchase
I purchased this mostly for fun-- and it was priced at a point that this is a reasonable use case. That being said, it seems to produce useful measurements and I will press it into service to analyze my household power use. I didn't rate its accuracy, lacking a calibration standard, but the measurements reported seem to be credible. I suspect it could be wholly relied upon for comparative assessment of power use. Absolute calibration is uncertain. Highly recommended-- apparently useful functionality for a very low price.

5.0 out of 5 stars Does what I wanted it to do
Reviewed in the United States on December 30, 2020
Verified Purchase
I have a couple of power strips from my computer/printer/speakers/etc plugged into an outlet. I know these things don't individually draw many watts, but I was curious of how many total watts being drawn. The meter measured exactly what I wanted it to measure. The instructions were cryptic, and they said to install a battery. Good luck with that. I suppose you could take the back off and look around inside, but it seems the battery will simply hold your readings when the meter is unplugged. I wasn't interested in that feature, so it's no big deal. I didn't check all the other functions and I spent very little time with the instructions, but for what I needed it was perfectly fine.

1.0 out of 5 stars Died after a few months
Reviewed in the United States on May 10, 2023
Verified Purchase
The product worked great for the initial few months I used it. However, I put it on a shelf for a few months, and when I came back to it, it is completely dead. Whenever I plug it in, the whole display flashes. I tried pressing combinations of buttons, I tried pressing the reset button, and I tried it in a variety of outlets. It appears to just be dead now.
