Needs More Teeth
This is the most durable twist grinder I have ever used. However, I was used to my old grinder with had twice as many teeth and left my herbs grind to the level I like. This new one could grind rocks, but doesn’t ground it fine enough for my tastes. I usally grind a second time in another smaller grinder to achieve the finest I want.
There’s no realistic way to hold on to this grinder. It’s too thin and impossible to hold onto both sides to twist it.
