Yeah, the old adage, "do it right the first time", has fallen by the wayside.."FAST" can cause major issues, poor quality and possibly accidents..I'm speaking from 41 years of experiences in manufacturing...Really no excuse, no matter the product...As much as the 5er's and TH's cost, I expect better, but if we don't push it and just make excuses for the manufacturer due to brand loyalty, then we've failed as consumers and really don't even have a right to complain
Where I've worked manufacturing mining equipment, solid fuel propellents, tires, ABS systems. brake calipers, ESC systems, by the time ANY of these products had been manufactured, they didn't have to be checked agin due to all the quality processes built into the manufacturing process...and EVERYTHING I've ever been involved with, had safety factors like you wouldn't believe, because if a system failed, life's could be lost...but I'm "Old School", and "Doing it right the first time" doesn't seem to apply in some fields of manufacturing.
A lot of these manufacturers will work with you and do some custom work if you interface with them in a curtious and intelligent way....so that's not just something only GD does...like you said, you got to know who to talk to, or better yet, HOW to approach and talk to them..
