Seems good, packed good. I will use it in one month and then will tell exactly

No problems!

Arrived on time, packed well, looks pretty, not plugged in

Works well only the volume is low

This “switch” configuration really is a programmable safety differential, it also adds protection for over and under network voltages, and the best thing when it detects a problem in the electrical network as a leakage current, Or over or under voltage is disconnected to secure the circuit and rearms automatically in the time you program it. All this and you can also manage it through the app yours (via wifi). And to finish it gives you data from your network such as the voltage, current, leakage current and the kWh that you are consuming. I have replaced the differential with this device to make sure that in case it goes out of the parameters that I have programmed it interrupts the circuit and rearmament when these problems cease.
