The Titanic director has made 33 dives to the shipwreck and visited ocean depths in a submersible he built himself. He compares OceanGate to the Titanic in that both ignored safety warnings.
Well, sorry to disappoint you but if a circuit endures higher temperature swings than another then it is of a better quality than the other one. This attribute is part of the quantification of quality. But feel free to explain yourself.
"Military grade" does not necessarily mean higher quality. It just means it meets the requirements of the military for a specific purpose. Could actually be pretty shit quality. But you'd already know that if you had read RoboRay's initial comment.
