There's no fucking way anyone can tell me you can tell a difference from the buzz of a keif catching grinder vs anything else.if you do your a liar or under the placebo affect
..
For those that like to smoke lot get a good quality non aluminum grinder( the aluminum dust will gradually flake off the grinder and get in your weed which is very bad).
The stainless steel (full of nasty heavy metals) grinders also create microscopic dust as you grind the metal on metal wheels just much less.

been using grinders for 15 years.you guys must be buying knockoffs or something.ive had these discussions countless times.your either buying chinese crap or its all in your heads
