The infamous Joycon drift is one of the biggest design flaws of the Nintendo Switch (along with the top right of the LCD screen detaching due to the heat generated by the processor)

With no sign that Nintendo ever fixed this problem with a better design, buying a new Joycon for 50$ seem a waste of money.

Fortunately, there are quick an cheap ways to resolve this.

If a brand is unbeatable for selling the same thing over and over again,  it's well Nintendo (Zelda for GameCube, Zelda for Wii, Zelda for DS, 3DS, ...). The Wii controllers are not forgotten in this game.
