A hand grinder's structure must keep its burrs aligned while the handle applies changing forces. CoffeeBox's guide therefore emphasizes shaft support and burr mounting alongside the cutting surface itself. That is a useful inspection theme, but counting bearings does not by itself establish alignment, durability or the flavor of the resulting coffee.
Try the actual workload if possible. Dose size, roast density, grind setting, handle length and grip all affect effort. A grinder comfortable for a small filter brew may feel demanding for repeated espresso doses. Larger burrs can process coffee differently, but diameter alone does not guarantee easier turning or a better particle distribution. Steel and ceramic also need model-specific evaluation rather than a universal winner.
Check usable capacity, adjustment resolution, cleaning access and replacement parts. Follow the maker's cleaning instructions; a washable component does not mean the whole grinder should be immersed. Manual and electric grinders serve different routines, so neither is automatically a beginner or advanced tier. Photos of grounds can reveal gross differences, but controlled particle analysis and brewing comparisons provide stronger evidence than claims of zero fines or a simple specification ranking.

A good question can make a better brew.
