The ball does not break as easily as others. Its roundness is comparable to other quality balls. The quality between each ball varies from time to time, but that's just a plastic ball problem.
The problem is the new generation of plastic balls broke and were totally rubbish. The newer balls are much better quality. I still find even the new generation of plastic balls from andro or Butterfly are all slightly different and not completely identical.
I have tried many of the new balls but the andro ball is my favourite because the ball doesn't break as easily as some of the other new balls and the ball is nice and round unlike some of the other balls
