We play on green clay, and they last..

Feels slightly heavy, but they have great durability on hard and clay courts.

Long-lasting and durable. Little weighted but good for Fast gaming.

These balls exceeded my expectations. I normally play on clay with Penn Championship Regular Duty. I tried these Babolat Gold and found that they have slightly more bounce than the Penn (more like a Wilson US Open ball in my opinion), and they seem to maintain the bounce for the next few days (for warmup). I'll be buying these again.

hands down, best balls for duration and staying fresh...

Luv these. Bounce higher, respond quicker than Penn or Wilson, on ALL courts surfaces—clay, hard, indoor. Can usually get several more games from them as well. Will never use anything else!!

Great performance. Long-lasting bounce.

Excellent balls to drill singles with for 90 minutes. Stayed very consistent on a hard court.

Great ball. Great price. Durable for a regular duty felt.

These balls are lively. They hold their bounce, firmness and the felt holds up well too. Much better than your average ball off the shelf at Walmart.

Delivered in record time. The folks I play with keep asking me where I got these tennis balls as they have a great feel and are lively.

Good price and the tennis balls and no fuzz problems.

These are crisp lively Tennis balls, well suited for US hard court play. They are slightly heavier than Penn balls that I also play with, but they maintain tension well through play.

Works great on clay even if it has been in a basket for 3 months
