I was so ticked off when I received my two joysticks and found out within the first 30 seconds of play that these are only for looking at, not for actually using. Simply put, this joystick attaches to your device with a single suction cup which does not keep the joystick in place whenever pressure is added to direct the movement of your on screen character. The Fling has multiple suction cups that are not directly at the point where you apply pressure to use the controller, thus it stays in place. When you try to move in any direction using this joystick, lets say to the right, pressure to the right side of the joystick will initially start moving your character to the right. Sadly your joystick also moves right until it slides off of the onscreen controller. I really wanted this to work because it took me back to tmy arcade days, but sadly, the people who made this were only concerned with making a cool looking joystick and never thought about how it should work. Save your money!
