If you play Mario Kart or other racing games on your Nintendo Switch, then getting wheels for your joy-cons is a must. Not only are they generally easier for adults to hold than the joy-con alone, having an actual wheel to steer makes the game more fun and often a bit easier. Wheels are available both from Nintendo directly and from third-party companies and most come with two wheels in a single set. Colors vary, but most match the colors of the joy-cons. Watch out for the fit of the joy-cons--if they aren't placed in the wheels correctly, you'll have issues getting the top buttons to register while playing.
