Neff has a (magnetic/removable*) knob as well.
(* Which is a great idea in theory. Unless you have kids. First it's great because they can't start the cooktop on their own. But then you are constantly looking for the knob. A friend nearly got insane...His daughter "accidentally" took the whole fucking thing on a schooltrip to France....HOW? That's why I have the Siemens one with touch.... It's okayish touchwise and it works...)
