All the grinders in our list are traditional (manual) grinders. However, there exist automatic electric grinders too, where you don’t need to use force to crush the weed. It is done electronically. Those grinders are more expensive and don’t really have a great reputation of lasting a long time in the markets - hence we haven’t included them in this list, but perhaps we will do a full article on them in the days to follow. Keep an eye out for that one!
