The Joy-Con Comfort Grip transforms the left and right Joy-Con controllers into a single, comfortable video game controller for Nintendo Switch. The ergonomic rubber grips are kind to your hands and fingers and prevent cramping during long gaming sessions. Simply slide each Joy-Con controller down the rails until they click into place. The player indicator lights illuminate through the centre area. In addition, the Comfort Grip stands up on its own, so you can display it next to your Nintendo Switch dock.
