I have several issues with my R50, but the biggest has been not being able to complete a full round. 95% of the time halfway through the R50 will freeze. Either frozen on the red light, not recognizing the ball or frozen on green. The frozen on green part usually happens after I hit into the green and it switches to putting. I have to hard restart, but I can never go back to the previous game. It asks it want to but when I do, it just freezes again.
