Input:
I upgraded to this model from a blade grinder--WOW!  I love the uniformity with which it grinds and that you can set the coarseness.  I have not had any problems with the unit...it does not spew grounds nor does it freeze up as some have said in their reviews.  If you have trouble with grounds leaking out, make sure the lid on the grounds catcher is on correctly.  It could be slightly decentered and leave a gap.
This is a all-around great product!
