Stable connection, high accuracy, deviation below 1 watt compared to the nominal operation of various devices.
The only "negative" is that it retains the last measured value, so if you open it and have a connected device that is turned off, it will appear to consume watts and the only way to realize that the device is off is to see that the daily kilowatt-hours do not increase.

I usually use them for two 2500w heaters. I program them to heat the rooms in the morning before we get out of bed. But I also open and close them when I'm on the couch or watching TV in bed and I don't feel like getting up.

They work great, without any problems. Perfect and easy initial connection and operation with Google home assistant.

Since I got my first socket, I haven't bought any other brand. They are flawless

Initially, very good build quality and a premium feel in the plastics. They have a very good fit and connected immediately without any problems. Also, Alexa found it right away, I didn't have to do anything, I just said "alexa turn on XXXXX" and it played. Very good and worth the price, super (21€ for 2) considering the competition.
