For anyone who likes to grind their own coffee beans, this is truly excellent grinder.  I've tried several different grind settings and get a consistent grind size for each setting....and, more importantly, a great cup of coffee.  The machine seems to be well built and the parts are heavy-duty.  While I've only had this machine for a couple of months, it has worked well with no problems.  Note that my four-star rating only covers early performance.  A fifth star could be earned depending on how long it lasts me.
