I have not tested this ball in rigorous scientific conditions, but I HAVE played with this ball much. I had always thought that you need a 3 star ping pong ball in order to have perfect play, so I bought some 3 star balls to start off with. Strangely enough, one ball came with my paddle/racket which was a 2 star, so I decided to preserve my 3 star balls to play with this 2 star one. It was great! I honestly couldn't tell too much of a difference! (barely)considering the price differences, I was very delighted at the quality of this DHS 2 star ball. I've tried some really terrible ping pong balls out there... most of them probably balls from those American sporting goods stores, and this is what I would call a quality ping pong ball. (I would still go with 3 star balls if you are playing competitively, just because you should know and feel the difference)I had just come back to buy about 60 of these balls for recreational practice, in the meantime, leaving this review.
