It hasn't been long since I installed it and it seems to work well. The only thing I didn't like is that when you switch it to display something other than the KWh, e.g. the instantaneous Watts, it stays for only a few seconds and then returns to the main screen.

Perfect. After the main fuse in the panel, you run the 6mm cable to the meter and from there with another 6mm cable it goes out and connects where it was connected before. As for the neutral, with a 1.5mm cable you're fine and screw it into the neutrals of the panel. The main screen has 2 readings (total kilowatts, one of which you can reset every month by pressing the button). I got it mainly for power measurement. You need to press the button 3 times and it shows for a few seconds the power you are consuming. This way, I see my 24,000 BTU air conditioner start at 2000 watts and in half an hour it consumes 500 watts. This way you save on electricity and only (when you can see at any moment what you are using)

Very good device for measuring consumption on the panel. I am not at all bothered that its display is constantly bright. I would wish it had larger numbers on the indicators, but it is difficult to achieve this in such a limited space it occupies on the panel.

Very good.
It has all the indications, Kwh, v, a, w, Hz & pulse.
It has 2 KWh indications where you can reset one whenever you want. It is easy to install. You can also secure the connection pole caps.
It will show over time how reliable it is.

Great. It works perfectly for a few months now. The good thing is that it has 2 meters and you can reset one whenever you want.

Functional, expensive illuminated, very easy to install. Make sure the neutral is with a good 1.5mm cable, not larger. If it had slightly larger digits, it would be perfect
