It works at different powers, up to 2KW. It is useful for those who do not have induction and for those who have it but want to move 'the hob' to a different environment (e.g., a balcony or simply another room).
The dimensions are not very small but still contained and can also be used with large pots (as long as they are for induction).
It is easy to adjust: you set the power, the duration and that's it. It has air vents on the side to dissipate the heat, so it should be kept in a position where the air can actually come out and not in direct contact with objects that do not like the heat.
I suggest pressing the lock immediately after setting it because this way you avoid inadvertently changing the program.
Acceptable quality/price ratio even if you can find something at a lower price, but with a more traditional design (e.g. rectangular black hob).
