One thing from an order years ago (~ late 2017): I bought two launch controllers (Std and E), and when I installed batteries in both and function checked them, the continuity pins on both were too small to provide continuity, so I couldn't get the ready lights to illuminate! In was somewhat upset about that, but I didn't have an immediate launch planned, so I considered the issue. Since the plugs wiggled in the controller, I decided ti try a 5/64" drill bit instead, and voila! it worked in both controllers! Don't know if yhou've noticed and fixed that issue in the interim, but to me 9it is worthy of a Service Bulletin.
