Got a long and somewhat narrow yard so watering was challenging.  Struggled to get the entire yard watered without moving an ordinary sprinkler.  This is awesome!!  Runs the hose down the yard and shuts off.  No fuss and gets the entire yard.  This thing can even turn corners.  I thought it was broken at first but it just moves really slowly even on the fast speed.  Really like how you can change how far and wide the water goes by adjusting the silver spray ends.  This can even move through thick uncut grass.
