For boiler itself:
+ The water boils pleasantly fast
+ Capacity display outside the container
+ Design and build quality
+ Good haptics
- Is quite warm outside, but you have for a yes Henkel
- Cleaning could make a bit difficult at the small opening, but enough in my experience a decoction with citric acid or vinegar
Conclusion: Solid stove in the beautiful design which meets all the requirements and to which I will certainly have long-term enjoyment.
