The Case ScrewBalls really do work, however they will not open every case the first time. A watch that has been used for a long time can get dirt and oil in the case threads and along with the gaskets will form into a glue that will seal the backs on certain watches that have not been opened for years. Another factor is how strong your hands are, since you do have to hold the watch in your hand.
What the case ball does for you is to allow you to open most cases without having to set up another tool and run the risk of scratching the case back. Another tool to open difficult case backs for the first time will still be needed. Again, what the ball does is save time and removes the risk of damage to cases.
