Carefully inspect the screen for scratches or dead pixels. Test all the buttons and joysticks to ensure they are responsive. Check the battery life and charging port. Ask the seller if the console has been banned from online services, as this can significantly reduce its value. Verify that the Joy-Cons attach and detach properly and don't have any 'drift' issues.
Typically, a used Nintendo Switch should come with the original dock, Joy-Cons, Joy-Con grip, AC adapter, and HDMI cable. Confirm with the seller exactly what is included in the sale, and factor the cost of replacing any missing items into your offer.
Ask the seller for proof of purchase or ownership. If the price seems too good to be true, it might be a red flag. You can also request the serial number and check online resources (if available) to see if it has been reported as stolen. Meet in a public place for the transaction.
There are several Nintendo Switch models: the original Nintendo Switch, the Nintendo Switch Lite (handheld only), and the Nintendo Switch OLED model (with an improved screen). The OLED model generally commands a higher price due to its superior display. The Switch Lite is typically cheaper as it is handheld only. Ensure you know which model you are buying.
Buying or selling a Nintendo Switch that has been modified to play pirated games or circumvent copyright protection may be illegal under UK copyright law. Be aware of the risks involved and ensure the console is being sold legally.
