The Nintendo Switch Pro-Controller is a premium product boasting premium grips and a semi-transparent casing.
It has the same buttons as the Nintendo Switch in handheld mode, and is designed to be held and operated more easily than the Joy-Con Controllers!
The primary difference in the controls is that while the directional controls on the Joy-Con (L) are made up of different buttons, the Pro Controller has a single + Control Pad, similar to previous system.
