Comments: Folks, do not buy this pack (tennis balls with cooler) expecting to use the Dasani coupons. They are
expired. The coupons that are included with this expired on 12/31/13. Other than that, the balls and cooler are cool to get.
Comments: I've always liked these balls. They play fairly quick and the balls don't fluff up easily. They play the same
over the course of a match, which I like. Some balls fluff up and slow down dramatically after just a few games.
Comments: Penn Champ Extra Duty is one of the best balls that you can buy. It is not too heavy or too light and
you a perfect amount of control and comfort. It plays for 4-5 times (8-10 hours) of heavy hitting before they start losing pressure.
And after using them for heavy hitting, you can always add them to your basket for drill balls where they will probably last you for
approximatelly 3 months.
