Good if its one with a kief catcher and after you buy it you TOTALLY forget that u have a kief catcher. if you forget then that kief will be a godsend later. if u remember then well id rather do it with my hands. Because that kief would be gone soon anyways. and a grinder in ur room shouldnt be too bad considering you have weed in ur room...

Editisregard im completely uneducated in the topic apparently. never used a grinder bought a grinder or touched a grinder just thought my post would be better than no one replying but that was fixed anyways.
