Joy Con 1 is a design disaster internally. I really question how they managed to get past testing sometimes. The original board on the right Joy Con that came with my Switch was so poorly made they even forgot to fully solder in the R button, causing it to literally fall off during disassembly. As a parting gift, the casing plastics developed a crack around one of the screw holes, causing the screw to no longer go in properly. I had to hack together a shell from a parts Joy Con I bought, since it was a special Smash edition Joy Con that I couldn’t get a new replacement of.
