It's only a matter of time since we bought the Nintendo Switch to have Mario Kart 8 Deluxe in our house. Of course, as the kart requires a wheel to steer, I was finally persuaded to buy a set. The Nintendo Joy-Con wheels come in a set of two and work great with Switch controllers. The wheels hold the Joy-Cons firmly and securely, making it easier to control the Drift (SR button) and Throw (SL button) functions. The wheels are small, like the Joy-Cons, about 5 inches in diameter (or DVD size). They are very light and seem strong. were good value for money with ease of use and comfort Overall this is a great accessory for all your Nintendo Switch driving needs.
