Do you think Stern feels when they ship a pin the code is good and done? Or are they knowingly sending out unfinished codes with a "we'll get to it later" attitude?
Personally I'll give them the benefit of the doubt and say they feel what they made is good and complete. Then we play the crap out of them and notice mistakes, and things that need improvements. Stern then has to go back and fix what they thought was finished which takes time.
I'm sure they have testers but their testers are no match for us
