This little power meter is great in many ways, but not so good in many ways. I like its small form factor and ease of use, but I don't like that you have to wait for it to scroll through all the different readings to get to the one you want, only for it to disappear before you can actually read it. It has potential, but I feel like a firmware update is needed to fix those and a few other pesky specs. It's also about 2% less in voltage and current compared to my Fluke and Siglent lab meters.
