Works great!!!!  Once you figure out which direction to put the watering tines...  So, I set it up and thought it was pretty easy but no matter how long I left the water running, it did NOT move!  And the rear wheels do NOT move if you try to do move them manually.  I was convince I received a lemon.  One call to support cleared it up!  Turns out you MUST turn the tines so they spin in one particular direction.  (It was in the directions AND there is a picture on the unit, but I'm a guy... so directions, shmirections!)
