WiFi Smart Plug Mini 13A&3300W ANOOPSYCHE Alexa Plugs with Energy Monitoring, Timer Remote Control Function, Smart Socket Compatible with Amazon Alexa Google Assistant IFTTT, No Hub Required (4 Pack)

Ordered two. One star deducted because one of the two plugs squeals pretty audibly :( ... sounds like coil whine. I might return that one for a replacement.I tried a few other "small" smart plugs out there and they usually overlap the on/off switches on wall outlets. This one doesn't totally overlap the on/off switch, but presses against the on/off switches creating a lot of friction. Still, it's visible narrower than the competition, and I can simply file off some plastic to shave some plastic to reduce width (that's how little it impedes). The other brands I tested which were larger (both round and rectangular shaped) were not squealing.I also tested them with our boiler which draws 12.95A and 3150W (measured with professional equipment) and they held up fine, even if they got hot (getting hot is totally expected at this high power draw - the boiler plug and cable get just as hot with or without the smart-plug).On the boiler, one of them reports 3147W the other 3195W .... that's a 1.5% difference, so I'm a little disappointed by the accuracy of measuring current/voltage/power, though it could be worse I guess.Generally happy overall.
