Really works well and as described. My ball would get some really bad belt marks and this product worked great to help remove them. Took a while to remove marks the first time as my ball has not been cleaned in weeks, but cleaned up much quicker after the first use. I was a little worried about it hurting the performance of the ball, but noticed no negative performance issues after use. If anything it improved my balls performance. I would highly recommend. I'm a 214 average bowler that bowls league once a week.
