I have the thermostat now for about 1 year in use for a single room control of underfloor heating. The built-in bimetal thermostats were too imprecise and not flexible. The connection was fast from equip since the old thermostat already for line, neutral and switch wire were placed and were therefore ported quickly to the new thermostat. The programming is not self-explanatory but perform well with the manual. The installation itself is not in accordance with German standard since only 2 screws are not suitable for a normal switch box. Simply use other screws and hope that the switch box is properly installed, holes in the switch box horizontally. The cover is put on something else, but this one makes a rule so only once. With us, the savings was after the first year compared to the enormous bimetal thermostats and I no longer want to give her. I'm waiting now on thermostats to be controlled with an app and not cost a fortune, so long as they remain in use. For me there is currently no thermostats with a better price-performance ratio.
