Bought a Star Glazer wake edition perfect pass system around 4 years ago for a Prostar 190 2001. I loved it ever since. I contacted the gentelmen at PP a couple of weeks ago as I became curious about a "z-box" upgrade to make the system similar to those high-end "zero-off" system most tournament ski boats use. Long story short, I installed it last night and used it for the first time this morning. It is AMAZING!!! timings for the course are excact same as specification. Big thanks to Gary, Mark and Carol from PerfectPass!
