Wind!
I am using mine to cover a wide area of my desert property. Mounted on a pole about 10ft up. Set the waypoints and worked first few days. Now the wind comes up and it ends up pointing at the ground. I have it mounted upside down to cover directly below. Once the wind dies down, I can reset the waypoints. Not sure if mounting it right side up would help but then I would lose my downward view. Bummer.
I guess make that two drawbacks?
