The cooking performance is very good, with 3000W power, the water is quickly hot. But here one should take care in any case that you touch the stove only at the designated grip. Since it is made of metal, and the stove itself is quite hot outside. But the handle stays cool and is definitely safe.
It is handy that the unit can hold up to 1.7 liters of water; is rather inconvenient that there are no visible external filling scale, but only a mark for the maximum level inside the unit. Very well constructed is the way of discharge of the device, even with fast pouring of water dripping next to nothing! One nice thing is that you do not have remove the lid to fill up, but leaves open a button and it snaps shut again then simply (here on the clearly audible click eighth, until it is locked).
Taking into account the excellent design and smaller weaknesses described, I give four stars.
