What is your expeience with the Porlex Mini II manual grinder?
It’s the only grinder I’ve ever used, I find it quite handy and consistent in the grinding but I have actually no benchmark to judge it objectively. Is it actually good?

Steel conducts heat. If you grind coffee with steel, there’s risk of slightly cooking the beans - changing the flavor profile.
Ceramic, in contrast, is an insulator. Therefore, it’s safer to use ceramic grinders for coffee.
If you handle a ceramic burr grinder properly, you can get consistent enough grinds quickly enough to make consistent, high quality coffee. Those of us who grind by hand don’t care as much about speed - we are grinding by hand, after all.
It’s not worth the risk to add heat to the grind process.
I’ll add that I don’t judge if people use steel grinders for their coffee. It’s your coffee, make it the way you like it! But ceramic grinders are hardly garbage, and Porlex does make some of the best hand mills.
Unless you are attaching your hand grinder to an electric drill, a person cannot apply enough force or speed to generate the high RPMs to generate heat. You are way off based on this.
You and I may disagree, but hot damn Timemore makes a sexy product.
