I purchased not one can of balls, but a case of 24 cans. They are used for match play & training & drills w/ 4.0 hitting partners. Their useful life outlives longer than Penn balls! So, if you are a avid player searching for a balls that tend to exceed expectations & on-court performance, the Wilson Championship is a top tier choice!

I had been using Wilson balls consistently for the last couple of years because the Penn ball quality had gone down the drain. I had no problems until recently. I guess with all the increased demand Wilson no longer needs to care about their quality. I've opened about eight cans out of the 24 so far and half have been a problem. Two were not sealed properly so there was a dull sound when I peeled back the aluminum lid. Two were sealed, but you could immediately tell the balls were dead. I've emailed customer service multiple times to no avail. Never buying these again.

In comparing the balls to Penn, the quality of the Wilson balls are so much better than any of the Penn balls. The balls hold their felt during the match. There are no irregularities in the seams. Compared to Penn, the Penn's have little tabs. The Wilson balls have superior quality control in production compared to Penn. I make this comparison because our club only carries Penn balls. When I bring balls, I receive compliments on the quality of the Wilson balls. Then my partners go and get the inferior Penn balls from the front desk when they have to supply balls.As a coach, I have stopped using the "coach" balls that other manufacturers offer. The Wilson balls hold up longer and the cost is actually slightly less per case. The other balls are good for 2 weeks as ... MoreIn comparing the balls to Penn, the quality of the Wilson balls are so much better than any of the Penn balls.

I am gettng almost a month out of the Wilson balls, cutting my cost in half. Thank you Wilson!
