PENN Pro Penn Marathon Extra Duty Case Tennis Balls

I am league captain of the NetChix. We began using the ProPenn Marathon balls almost 3 years ago, and have never used anything else since! Advertised to be %22 longer lasting than other balls, we feel it is more like %50 or greater! They bounce higher, travel farther than any other ball we have used. I recommend them to all my tennis friends, try them people, youll never go back to something else!

Ive purchased racquets, accessories, and balls from Tennis Express. Very pleased with the fast and efficient service

I use these balls for my weekly 2 hour serving sessions, 8 cans at a time. They last for about 3-4 sessions, which Id say is at least 25% longer life than other extra-duty usta approved balls. Will buy a case again soon.

First rate product from Penn. Outlasts their championship ball by 30% approx. Cover retains bright yellow color far longer on all surfaces.

I will not buy any other ball. Very lively and lasts 3 times as long as regular balls. I have been playing for 30 years and am very happy with this ball.

I played with these balls over a period of several weeks and found them to be longer lasting, brighter, and higher bouncing. They definitely improve play in weaker players because they dont have to swing as hard. Meeting the ball late will cause a weak swing that will go into the net with other balls, but these will make it over. They will help play with beginners. Experienced players would like the extra drive these balls deliver. Consequently, they give you more satisfaction in your play.

Long lasting and good feel for play on hard courts. An improvement on the Pro Penns! I think they are the best balls on the market.

The Pro Penn Marathon Extra Duty tennis balls live up to their name. A can of balls lasts through 3 sets of hard tennis and continues to serve as a great warm up or practice Ball after that.
