I bought this pack of six tennis balls for weekend games with my kids and some casual practice, and they’ve been great so far. The bounce is consistent, they feel solid off the racket, and they don’t go flat quickly like some cheaper balls I’ve tried before. They work well on both the court and just for backyard play.
