It is an ok, entry level, electric kettle with 2 x 1500W heating elements and an integrated temperature controller. The kettle. However, there is one issue with it, the temperature controller is bad. The way it is working is by turning on heating if temperature is below target minus 3°C, and turn it off when temperature is above target plus 3°C.
