I bought the Innovative one ball Revivor a few years ago. it has paid for itself. The temperature is factory set at 140 so we can't screw that up. It does an exceptional job.

In years of working in and around pro shops I like Innovative as they have always had good customer service and parts for my spinner when needed.

My experience is that until you get 50 or so games on a ball, assuming you clean them after each use, you won't be pulling much oil out.

Not all covers are the same, even within the same brand, but I'd wait at least 30 games to check to see if there has been much oil absorbed.

Of course, until that point I'm resurfacing very regularly to maintain the desired reaction. Hope this helps.
By the way, since all my teammates have me doing their bake/resurface work my Revivor has paid for itself.

5-10 game cycle won't hurt the ball, it's just whether you want to spend the time.  The factory setting at 140 degrees is considered safe, so there's probably no down side.

HOWEVER, once finished, I like to let the ball return SLOWLY back to room temperature before resurfacing. If you place your ball in that often make sure you have time to let it return to a normal temperature to avoid extreme changes.

Living in Utah I have worked on several hundreds of balls between the Pro Shop and home, many Storm products and Brunswick family products with nothing but grateful bowlers when performance has been restored to their equipment that is getting more expensive.

I have never seen a ball that absorbed oil (enough to hurt motion) that fast. Since every ball ever made needs to find friction to change direction, we're just not rolling it through enough oil for it to be absorbed that fast.

All I can say is some of these balls have hundreds of games on them and can still perform very well when the oil is extracted AND the surface texture matches up with the bowler and their lane condition.
