Comments: Just received my order. Almost half of them felt flat right out of the can and one of them seemed open already. I'm not happy with the quality.

Comments: I bought these for my ball machine. They were good fresh off the can but, as others said below, their longevity is terrible. The felt hold out pretty good, but they barely bounced after a few hitting sessions. I had used other brands before that fared way better, and for far longer. If these would be sold for half the price advertised now, I would still buy them as I could afford to change them often. But for what they are asking now, I'll pass.

Comments: I bought a case of these balls then injured myself and was out for several months. When I came back the balls had lost their bounce though the cans were still pressurized. Several players at my club have had the same problem with Penn balls. Penn said that the balls were expired and only replaced three cans.

Comments: These balls are only good for a set then they're done.

Comments: We opened two cans of Penn balls last night. One can of balls was noticeably lighter and hollow sounding when you hit them. The can I purchased was quite heavier and harder when they were hit. Both sets of balls lasted through four sets of doubles with just the right amount of fluff for me. Both sets were also bright yellow and good enough to use again as practice balls.

Comments: I agree. Penn Championship used to be one of the best tennis balls out there but it's durablity went down by a whole lot! I meant to contact Penn about this. It fluffed up after 15 minutes of hitting and felt really light. No matter how hard you swing at it, it doesn't go and it's easily carried away by the wind. Not sure what happened!

Comments: Something changed with these balls, and the ones from the case purchased from TW are different than others of same type/brand that my playing partners bring. The color is a brighter yellow, and they fluff within minutes. So bad that I open a can just for warmup and then discard -- they won't last through a set of a match without severe performance degradation. Used to be a go-to ball for reliability and durability, but no way would purchase them again. I would be curious to know if others have had this same experience.

Note from TW: Hi Matt -- We will talk to Penn and see if they have made any changes in production. Stay tuned!

Comments: We just played the Middle States Sectionals using Penn extra duty tennis balls. They were very light and fast. I couldn't imagine ever using them again to practice. The Penn ATP ball is excellent, but the Championship balls are the worst ball I've ever played with.

Comments: These balls crack too easily.

Comments: I like these balls. They are fast, don't fluff up, and don't lose their speed over the course of a match. I like a hard, fast ball -- so these are great for me.

Comments: I found these balls simply put and more than anything else, don't bounce consistently. (There are other issues with these balls, but their unreliable bounce is what is most important to me.)That might not be a problem if you're a mile behind the baseline and have time to adjust, but, for me, who starts his swing often before the ball hits the court, it's a big deal. I routinely half-volley shots off the baseline, and Penn balls aren't reliable for me.

Comments: I have been playing tennis for the last 20 years. I bought a case of Penn XD tennis balls a few months ago. They were the worst I'd ever played with. They did not bouce well at all. I hate it. Those tennis balls were terrible.
