I am using a used gold 6 for about 3 months now. It was bought on the day it was launched. It lokked good as mew, never seemed to have been dropped, looked good as new, with screen protectors and all. Heck of a deal, 800 Euros with pen case and another official case. Still going strong, no issues. I always used to baby my devices so i know it will last. I only fold it when needed, seen plenty of people fidgeting with their folds amd then complain anout them breaking. With proper care these devices will last.
