This sprinkler worked great for the first two months, watering large areas of the yard a traveling along the hose as I had hoped, only occasionally jumping the ramp where I placed it. On one occasion, it jumped the ramp and ran until it hit the fence. When a couple of the interior plastic gears stripped out, it was a very quick decline when the remaining plastic gears stripped out and it became a stationary sprinkler. Now, it's useless and in the garbage. Design would be drastically improved with metal gears.
