I am a good pool player.i have never i my life scratched the Q-ball 67 times l one game, no matter what you did it scratched, also the foward English is on the ball all the time, and at slower shots the worse it gets. and the craziest thing i have seen so far is l took a shot at the 10 ball right in front of the pocket no way to scratch l shoot at little high seed. The Q-ball went around the ball l was shooting at and into the pocket Never Touching anything. just like something was Preplained
