Herb grinders are great for grinding up your Cannabis, whether to roll it up or vape it.  Either way, you need to grind your weed into small little pieces for it to smoke or vape effectively.  Having tried many different herb grinders, I have to say this one definitely tops the list for overall quality and ease of use.

The grinder measures 2.5 inches in diameter and 3.5 inches high.  Definitely not small, but not too big either; just the right size.  I decided to test this thing out, so I grabbed a nice juicy bud of Blue Dream…  Super easy to use, just lift the glass cover, and place the bud on top of the grinding posts.  Place lid back on grinder, push down and then start turning.  After about 5 or so turns, I had nicely ground bud ready to enjoy.
