This is a cool one with knobs that can be removed. Never used one, but I liked the idea.

Love it. Removable magnetic buttons with flat flush surface underneath that’s just as easy to clean as a touch surface. The only downside is the possibility of losing the knobs.

Downside for you, profitable upside for the device manufacturer who can sell replacement knobs to locked in customers at ridiculous margins.
