I have a total of 4 joycons, the ones that came with my switch and the ones I bought. From a company that's been making products since the dawn of gaming, these joycons are a sad excuse for controllers. Aside from the fact that R&D obviously didn't do their homework on what controllers should be. The QA obviously didn't pay attention or even bother to the details used. The analog sticks are TERRIBLE. Even with diligence, they managed to "infect" the stick drift problem, and no amount of cleaning will fix it after a while. Conveniently, these problems also occur after the warranty has expired. If you want to buy more controllers for your Switch, do yourself a favor: buy a controller adapter and use a reliable controller or a cheaper third-party controller that offers better reliability
