Quoted from BertoDRINK1:Ok just saw that on the website also, I'll swap those balls out. After the the cleaning and wax of the though it hasn't had any more issues but I'll still swap them out. Actually just broke my GC score on it.
Thanks for the heads up guys
I used those in my SM and had all sorts of issues with them registering in the trough. Went back to normal pinballs and haven't had a problem since. I only used the Ninja balls in non magnet games like IMDN.
