I have used these balls for several years and they are superior to regular Penn and Wilson balls. These last through 3 hard sets on hard courts and still have enough life as practice balls. The less expensive balls seem very light and lack substance. Only the Penn ATP balls come close. These are worth the price.
I am a 4.0 level player and I am using this balls many years. This is the only ball last for 3 sets, all other balls last only 2 sets.
i've been shopping around balls a bit over the last year. i play 5.0+. i find wilson balls are good at first, but fade quickly and penn balls seem to split quite often. these dunlops hit nicely for about 30 minutes of solid baseline games, but then become fluffy marshmallows. i don't think i'd buy them again, but their not bad.
All balls lose a bit of bounce after play begins. I am just a club level player, but lesser balls need to be replaced after 2 sets. These Player Elite balls keep their bounce through the entire match.
