They shipped out early this week from the west coast. When my ball driller gets them in, he's going to install one (at no charge for the first one since I'm the guinea pig) in one of my balls. I'll try to remember to bring my camera to show how it works. I glanced at the installation instruction sheet and it looks like a well-engineered system. They went to a lot of effort to make sure the insert stays in the ball and doesn't break it looked like.
