Nintendo's Joy-Con repair service is great and I never hear people talk about it
I just got back three Joy-Cons that I sent them (Nintendo USA), two of them that were out of warranty for a long time, and one more recent one. One of them had a *broken* joystick, the rubber was completely falling off on the sides. The other two had broken railings that made it hell to play Splatoon handheld as they would always detach themselves in the middle of the game, and one of those two was drifting.
I got them back fully repaired (or replaced?) in 2 weeks and it cost me 0 dollars. I was kind of expecting them to at least charge me for the damaged one but in the end they didn't.
I often hear people talking about buying new Joy-Cons when their old ones start drifting or break, but I never hear people sending them for repair, is there something I am missing?
EDIT: I understand that it is frustrating in the first place that Joy-Cons are so flimsy and need to be repaired so often, but the free repair option is a much less frustrating one than just buying new ones
Also the Blue and Red were replaced, the Zelda one was repaired.
