Five minutes that save you a headache:
- The seller’s Nintendo Account removed and the console reset, in front of you.
- Connect it to the internet and open the Nintendo eShop: it must connect. If it won’t, ask why before you pay.
- The sticks: in a game, the character mustn’t move on its own when you let go.
- A game for a few minutes: listen to the fan and test the controller, sticks and buttons.
