I bought this specific stove a few days ago. They have very good build quality, they weigh about 11 kilograms, and replacing them with the previous ones I had was very easy. Their construction is in Spain, although the characteristics of the stores indicate Germany as the origin. The glass cleans better with a microfiber cloth, otherwise it leaves smudges.
In their operation, they are very easy to use and the twist pad facilitates their use. If it is removed, the stove automatically shuts off, which is an additional safety feature. Also, if there is no cookware on the stove, it does not activate. The stoves work without the twist pad, but the power booster function cannot be used and the operation is slightly more complicated. The twist pad costs about 60 euros to replace.
It can also be connected to WiFi, which does not offer anything substantial. Regarding the boiling time, their speed is faster than a kettle, and the noise during use is not particularly annoying.
I would definitely recommend them.
