Using the sliders can be difficult, I have Electrolux for the second year and I swear that hey.
I used to have a Mastercook with power pre-selection and +/- support, it was much more accurate, i.e. I still have it, for a rainy day.
Bosch with the initial selection of the field and only the power setting will be a pain.
I use a 90 cm slab, a fairy tale!

Mastercook

Before buying the board after the Mastercook failure (I finally repaired it by buying the whole power module - used) I wrote with the service technician of such equipment, because I liked Sharp, he
Quote: The fact that the brand is known, but from RTV equipment, less mobile phones, because it was mainly produced for the Asian market. Household appliances are only 4-5 years old.
I will not speak about Sharp, because I was only in 4-5 devices. But the build quality is average. The fact that the purchase and then parts are not expensive.
As for Amici, she used to do pretty good inductions. Now everything comes from China and the quality has dropped significantly.
As for the Amica, Sharp service, it all depends on the specific service point and service technician. The fact that someone in some service point did not fix or something else does not mean that the given brand is bad. If you take Amica, you have to take into account that often the delivery time for parts is quite long (2-3 weeks). I see that most of the parts for the Sharp board are off-the-shelf (e.g. one power module: Link). To Amici: Link). So you can see that it is made to order and the price is much higher, but here I see that it is still on these good EGO modules (but they also fail. I have such a board myself, but with normal dimensions and one field does not work (always the front right one)). But for me it doesn't bother me at all. Who cooks more than 3. Usually 1-2 fields are occupied.
AEG / Electrolux is on the Tiger series modules. e.g.: Link. 9 out of 20 such discs have a trivial defect. This 1 is the fault of the service module (usually those that have sensors in the lower right corner). But so far I've had 2 or 3 such glitches.
Bosch / Siemens has recently had a slip-up with the inductor connector burning out. Mostly expensive repair (about 3/4 of a new slab). Or I disconnect one damaged one and the client continues to use 3 fields.
Beko is the same manufacturer as Sharp and it is also different here. Some hob models cannot stand ordinary enamel pots.
Candy/Hover used to be good, now comparable to Beko.
Whirlpool in older models usually flew the left module. But the shipwrecks were relatively cheap, so it was reasonable to repair it.
Samsung is one big failure. It breaks down to power, and the price of parts knocks down.
Teka either has a construction like the above Amica or Whirlpool, only the price x1.5, for the fact that the inscription TEKA, and the module is the same. Once a client agreed to a repair - a new module for over PLN 2,000 and I came up with it, because something TEKA is screwing up....
Indesit / Ariston - I will not say, because maybe I had 1-2 and it was a long time ago.
Miele, Smeg - I didn't.
Kernau - trash.
Zelmer - The older one was based on the design of the old Candy, the newer one is a total China.
