Cyclop balls came out in 2013. Any issues they had were fixed by 2016-17. All balls after that were fine.I had a set of Cyclops and they played great.
However, though my memory is a bit foggy on this, as the company ramped up production they moved to a bigger facility and some of their machinery got out of calibration and some sets were released into the wild that were out of tolerance. So, some balls rolled off and the number on the one balls cracked in some cases.
But if you got a good set they played great.
