The auto-dispense function is very cool but I warn that whatever you grind must be dry. Very dry, otherwise it will clump and not function properly without tapping constantly. The dry herb I use is super sticky so I have this problem. The flower also sticks to the teeth and it advertised that wouldn't happen. I'm not sure the magnets are properly aligned at all because herb gets stuck to them as it grinds. That shouldn't happen. This grinder also doesn't have a keef catcher so you lose that as it cakes onto the clear plastic separator on the inside. Cool idea but still has some kinks.
