Very good & with many capabilities !!!
I have two devices.
The only problem I encounter is that it sometimes freezes when switching from automatic to manual

In the positives, it measures kWh, can also be used as a switch, and has on-off programs.
In the negatives, its display is not illuminated and is somewhat difficult to see, and I also noticed some limitations in the range of its Wi-Fi reception (weak antenna?) and it frequently disconnects compared to another Wi-Fi device I have next to it, and it does not show me the same disconnections.
