I have some questions for those that have used this product:
What do you do with the finger grips? Do you remove them before putting the ball in the unit? Also wouldn't it hurt the thumb slug or outer sleeve of a switch grip? Do you have to remove these as well?
Just curious as I have always thought about trying this process, but never have. And I would love to have one of these at home if it isn't too much of a hassle with the grips/slugs/sleeves. Also going to try and get our local pro shop interested in it too.
Sorry I'm a little late on this subject. Thank you, Steven and milo, for giving your experiences.
I left my thumb inserts and finger inserts (I use the Super Soft Contour Power Grips; if anything's going to melt under heat, it's these babies. ) in when I tested a ball to see how long it could go at the highest setting.
I left it in for 3 hours and 45 minutes at 155 degrees. Ball, and inserts showed zero damage as near as I can tell from all outward appearances and throwing the ball later. Also no plasticizer came out; in theory it is supposed to start out at 150 degrees. FYI I also put a fairly accurate meat thermometer in there with the ball to check the temperature.
