Query: Ping Pong balls, what more do you want?

Okay so some of the balls arn't exactly round, but this is still a great deal, and great if you have a Robo-Pong 2040. $30value (Free 4dz 40mm Balls, Train Book) or something similar. it says 3 stars on the ball, but they arn't exactly 3 star balls. You are only paying about 33 cents a ball, so how can you complain?
