Review: Easy to use power meter - 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.
Review: Useful tool that will save hundreds of dollars. - I became president of a small fellowship and was looking for ways to cut waste. This tool helped me identify old, energy guzzling equipment that could be thrown out and would save us thousands of dollars. People just don't want to get rid of old "free" stuff that really isn't free because they aren't energy efficient. It doesn't fill all plugs, but most.

### ⭐⭐⭐⭐ Good for the price
*by A***2 on November 23, 2020*

I used this to determine loads for sizing a backup generator. Works fine for running loads but the sample rate is only every few seconds, so not very useful for capturing start-up loads. There is a peak function that records/saves the highest load, but if it's not sampling when the peak hits, you won't get an accurate reading. That said it was good enough for my use and much less expensive that other (probably more accurate) options.
