I love 1zpresso’s grinders. My JX-Pro is a real legend but there are different grinders for different types of coffee. For example, the 1zpresso ZP6 (which is back in limited stock) is largely considered the best hand grinder for modern speciality filter coffee.

I really enjoy the heptagonal 1zpresso Q2 for Aeropress and V60. I picked it because it fits inside the Aeropress plunger and seemed better than other grinders at similar price range in AliExpress. For these use cases grinding is smooth and not slow, and if I have to nitpick cons: removing the handle leaves it open, so I am planning to 3D print a cap, and the numbers on the clicking system do not align with the actual zero so you have to count clicks, or remember where the zero point is. If you pick the Q2S, the handle will also fold. If size is not a constraint, also consider Kingrinder K2/4/6, seem like good options.

This is what I use: https://www.amazon.com/gp/product/B092MDTGGR

It’s the first one I have ever owned so I can’t say how it compares to others but it works fine for me.
