I just scanned the thread for it on the tesalmotorsclub forums. My (admittedly quick) reading is that it had lots of f/w glitches early, and that there are charging limits imposed by 3/Y and newer S/X which lead to the glitchy reputation. And that's multiplied by the general unreliability of non-Tesla chargers, so that makes things even worse. That said, I have an older Model X where there is apparently no artificially imposed limit. If Tesla chargers become much more occupied due to non-Tesla's using them, I might pick up one of these adapters for my next road trip.
