Yeah, mine's the Pikachu/Eevee one too. So replacing it isn't going to be possible, and if I send it in for repairs I might not get it back. :(
If/when it goes completely I'll probably have to get the Splatoon joycons. I mainly play handheld so the Pro controller's not an option. (Though since it works with steam apparently, I might have to get one at some point for Ori & Spyro.)
