Their slides are made out of hard plastic,so they hurt you're in step. They charge you for shipping even though your amount is over the free shipping amount. Then, when you return the product, they charge you for shipping again.

Best tennis balls ever. Very good quality and last long.

I use the tennis balls to practice serving. So far I have used them for 3 days and they are retaining the pressure very well. I used them today for the fourth time and will now re-pressurize them for 48 hours. Based on my using the balls for practicing my serve only and re-pressurizing them after a fourth use the balls should last me until the end of September. Thank you. I love these tennis balls.
