The first concern for squash beginners is that the ball doesn't bounce as much as they expect. One reason for this is that many courts use double-dot balls, which are also used in matches. This product uses single-dot balls. Please refer to the following information, which is quoted from a website: 【Chukyo University Sports Museum】 Advanced players use smaller balls that don't bounce much (black double-dot), intermediate players and those for practice use balls that bounce 10% more (black single-dot), beginners and juniors use balls that bounce easily (black no-dot), and absolute beginners use balls that bounce even more and are larger (blue no-dot).
