Fucking amazing is right...I get fuckin chronic buds and always throw my bud in the grinder with the kief screen and it still smokes like chronic. I'll usually sprinkle sum kief on top a bowl or dip my cig into the kief pile for a lil buzz on the way to class..Im 110% for grinders with the catch..how could u not be?

o ya and if ur getting damp weed or some dried up shit, hey man it aint the grinders fault.....u get poop weed!
