I've had my switch about 18 months and 2 of my 4 joycons have had to go in for a Drift repair - each time costing half the price of a new joycon!
I am VERY careful with my gear and my son is too. They are just straight up bad design.
And here are my 4 Game Cube controllers that have been thrashed through Melee, Brawl, Smash U and now Smash Ultimate and yet they all work PERFECTLY.. Jesus, put THOSE damn sticks on the Switch...
