Quoted from iceman44:
Ever see Stern do that? Just sayin, I still love my Stern pins but at least JJP seems to care about QC and service and want to get it right and make every customer happy! The true test will be is this the normal mode of operating not only today but next year and 5 years from now, if so, they have a winning formula.......
Apparently you never looked here-

Pretty detailed and when a problem is identified its taken care of pretty well IMHO.
As far as support I have had zero issues with Stern. The one time I needed to call the factory they swapped a CPU board with me , no hassles.
As far as JJP its good to hear several people are involved trying to resolve any issues but its hard to award brownie points when the issues were built into the machine (software) or hardware (adjustments or changes) needed to make it work properly.
