this thing grinds like a champ. smooth as shit too, i'd just watch out for the teeth on the threading because my friend and i both cut our fingers the first day i got this. the vibrating chamber is awesome its a 5th chamber below the kief one and you can take that component out if youd like

Sharpstone makes some absolutely impressively well manufactured grinders. After I used one of these bad boys, I immediately began to regret all of the money I had wasted in the past on those cheap little herb grinders... this is absolutely worth the money, couldnt speak higher praises about sharpstone...

Awesome grinder. it doesn't come with a clear top like in the pictures tho, which kinda sucked...

bought this 6 months ago. this grinds like a champ. never got stuck once and plenty of herb has been though it. and the keef build up very slow but its some dank ass keef.

This grinder is very good and is very high quality. There was no clear glass window on the top like in the picture, and it grinds very well, and collects kief pretty well.

This grinder is the shit, it's fucking sick

Grinder is tha bomb diggity, soo much keif it accumulates!!
