I've had this Joy-Con for less than a month, actually less than 3 weeks. Haven't used it much since then and made sure to take good care of it. I tried to use it today, the left joycon doesn't even light up. My Switch doesn't recognize it and I literally can't use it. And that's after I had to replace my original left joystick due to a drift issue. I used to think Nintendo's quality was the highest among Sony, MS, and Nintendo, but lately they've been seriously disappointing. I can't say anything positive about it as I want to play around with my Switch whose hardware was so bad these days.
