The water can only be heated via the app, so you can't heat the water below 100°C without your phone. (So if your phone is dead and you want to have green tea - you can't). I don't know if it's just a defect in my piece or a problem with the whole series, I've claimed it, so I'll see.
It has the potential of a smart kettle, but the functions are rather limiting for the user (especially the non-functional temperature control): )
Nice look and black variant
Modern
When you select any temperature on the physical panel (40⁰ - 85⁰) it always heats the water to 100°C - so the physical panel is not working as it should.
When boiling the amount of water per min it makes a very unpleasant squeaking sound.
If you dirty the kettle with something greasy (e.g. oil), you can't wash it, you can see the spots.

quite well made mechanically
rebranded Tuya, so it can't be connected to home automation.
poor temperature holding, fluctuates
doesn't have a concourse to see if there's water. It will start even without it.
after approx. half a year the wifi connection stopped working

Fast heating of water to the desired temperature
Temperature maintenance up to 12hrs
Possibility of timer when the water turns on
Used for 2 months to heat baby water - not recommended. There was limescale forming in the kettle every day, so constant cleaning of the kettle with vinegar.

Simply a solid can, corresponding to the price in a very good design.
Perhaps only at the selected temperature it tends to "stumble" sometimes, i.e. adds heating power, then reduces, then adds again, even if it has not yet approached the specified temperature.
Product of Czech company
Serves well, provides everything it should.
Looks nice.

I don't like her at all, but I haven't found a better one. It is hard to use, 2 possible settings are not intuitive at all and I think the setting of the countdown for how long to keep the water does not work.
mobile phone waving
does not have zigbee but wifi
can't keep the temperature properly, it fluctuates +- 20°C
occasionally heats the water to 100° instead of the set temperature
if the time it is set to keep the water at x° and after reaching the temperature I pour my tea, it continues to temper at x°, it does not turn off until the timer expires

I am satisfied with the kettle. But what was disappointing to me is that in April my claim period expired and about last month the kettle started to go wrong and it's hard to press the button to turn it on.

After a year, the lid attachment broke. There are two plastic grips and combined with the temperature changes, it didn' t hold up.
