I just got my Vertex mold ball spinner through the mail today and I used it. I only did some cleaning of my balls before league tonight. The ball spinner works very well and is pretty quiet. Mine is the 1/2 HP model and every time I switch it on, the lights flicker a little but it is just like a normal power tool. It does wobble very little, but is nowheres near unmanageable.
I have some plans to resurface my original X-factor. That will be quite a job considering I have well in excess of 300 games on it.
