I've had this model grinder for about 8 years now and it still works like a work horse.  I use it once or twice a day, every day and get the perfect grind for my coffee beans.  I am going to order the spice grinders.  They're a great idea too!  
I like that this grinder does not take up any substantial counter space either.  I leave it plugged in right beside my coffee maker.  You won't be disappointed with this little gem.
