I was buying a new kettle because the old one didn't leak, this one leaks after 1 month and it's on scalding, splashes water all around the lid and on the handle, totally kills all the pluses

I wouldn't buy it again, the older model was much better and lasted over 10 years.
Nice new design and better control buttons
It doesn't beep as loud
unlike the previous version, it does not turn off in 90° in time and cooks
cooks unnecessarily long at 100° before shutting off

Temperature settings of 50, 70, 80, 90 and 100° with colour resolution. That's excellent.
A bit poor access to the switch and temperature settings, also not good to get inside when cleaning.

Unusable to dangerous at 100°C, normally boils water at 90°C - it's a few extra clicks, and the need to always warn visitors.
Nice shape, glass, sealing strainer
Lights and beeps can be eliminated (handy daddy removed the speaker and put the lights in the handle so the kettle signals faintly to the table)
Temperature setting option
Good kettle when used at 50-"90"°C
I bought it thinking that according to the reviews it "cooks for a long time", but how long I really didn't expect. About once or twice I had the nerve to try it - clouds of steam and spewing hot water around.
It normally boils the water to 90°C. It is a total of five button presses - 1xON + 4xPlus. I've already learned it automatically and it doesn't bother me. Or I only cook at 50°C, that's just two presses. When one stands by it, the brew is finished by lifting it off the pedestal.
It doesn't remember the last setting, so I always have to re-set the desired temperature.
It seals well, which also means that it dewed and the beauty of the glass faded a bit - but clean dry glass and limescale in the mug, I've had enough of that.

Why does every button press have to be announced by a beep? And why does it have to tap when it's boiling water? Apart from the nerve-wracking tapping when boiling water is splashing all around, boiling drops are everywhere. And that's even if it's nowhere near full. In addition, due to the rounded shape of the top, it cannot be completely poured out, so some water always remains inside. I definitely wouldn't buy again.
boil water
can be heated to manual temperature
beeping when pressing the button
Did I mention the piping?
cannot be emptied completely, there is always a little water left
splashes water everywhere when boiling even smaller volumes of water
