90% of keyboards I see for sale, have either scratches, dings, or both. Even the aluminum ones which are supposedly tougher have them. I have no idea why they always have surface damage, unless the previous owners throw, knock against walls/corners, drag on rough surfaces or smash them out of rage.
I have carried and transported my keyboards several times in the past and none of them have sustained any damage, and I wasn’t even trying to be ultra careful with them. It seems so hard for me to damage keyboard cases unless I intentionally do it, therefore I really don’t understand how people manage to ding or scratch their boards.
I’ve scratched a couple of mine pulling keycaps, moving other keyboards around, while building my pc. I even scarred a spacebar with a soldering iron once.
Shit happens, it’s ultimately a tool and I’m not going to be heartbroken if a tool shows some use.
