Anyone running the Passon 18 spline OD gearset? I am trying to make a final

I am trying to make a final decision on which way to go and I want to get some input on the OD gearset from Passon to see if they are problematic or if they are any good. I have heard good and bad about them and I have heard horror stories of bad customer service when there are issues. Any input on experiences with this mod would be appreciated.
