Wilson US Open Balls Carton (24 Cans)

i use them on cement court
good balls, last long, most maintain bounce till the end
got them for 6k

Tennis Hub usually stock these balls. But if you don't get them buy Techifibre or Yonex Tour, all three at made at the same factory in Malaysia.

Perhaps the best balls in the market today. Shipped to Gurgaon within 2-3 days. Very good service from Tennis Hub.
True bounce and the Extra Duty felt makes it last. At club level they easily last three hours of singles play and about 5 Hrs of doubles play.
On the abrasive wall too a set of six balls lasts me six to seven hours.
We have come a long way from those oversized low pressure Symonds balls that often burst on the courts. Specially when we graduated to better Dunlop Max 200 G from those Symonds XL 1 wooden frames. During the old days Symonds balls were not even pressurized. They came in a paper box of six!

got them for 6k, even better than the Wilson Championship Balls extra duty(they go bald after going old but this one does not)
maintains uniform bounce with age, got for 6k rs after discount
best hard court ball i have come across, does not over bounce like dunlop Fort all court tennis balls
