well....since i got the ball, i see a lot of dust or grinded material got stuck in the balls shell, and it wans't really smooth, but if you had the correct position of spinning it would be smooth sounding.

and today, the ball just went wacko, and now it's sounds really loud, and grindy.....can barely reach 10k while it sounds like i can get to 11k when it was normal sounding.

anyone know what happened??
