480 cm high, the equivalent of 4 metres 80 centimetres high for the next generation of superhumans?

The base diameter and opening diameter are both stated as 30cm. Judging by the photos, this cannot be correct. Either the top is larger or the base is smaller. What would be correct?

Can I also use the pan on an electric hob?

Is the pan coating without PTFE/PFAS?

In the product dimensions it is written that the diameter of the opening is 28 cm, but also that the base diameter is 28 cm. How can this be the same if the pan gets smaller towards the bottom? I also have a pan at the moment, which also has an opening diameter of 28 cm, but only 20 cm at the base. That's what I'm actually looking for. So will this also be the case with this pan? Can anyone tell me? And then I have another question: you can also read here that there are 2-3 people who are very dissatisfied with the non-stick coating of this pan. Can anyone confirm this? Or is there a good alternative? Thank you very much.

Why is this pan so hard to get hold of?

I chose this pan because it combines stainless steel with non-stick properties. Unfortunately, it was never really non-stick, especially not as described with "best non-stick properties". Example: A fried egg prepared WITH fat (e.g. ghee) leads to a very stubborn bond with the ceramic seal with the result that I have to soak the pan or even boil salt water. I clean the rest of them only by hand. With my (well-baked) iron pan, it sticks less... What are your experiences? Did I get a bad production batch? Thank you.
