I ended up NOT using this for my Ring doorbell. The reason I did not use it was because I felt it was not secure enough to the Ring device and it appeared to make it easier for a would be thief to damage it or KNOCK it off the wall. That is why this item is now in a cabinet.
Does exactly what it is supposed to do. It changes the angle of the RING doorbell and it flips from one side of the door to the other. Screws lock the angle in place, loosen the screw to change the angle.
