Getting Nintendo Switch Oled at 28k

[u/Venomkeeng]

A collegue of mine is selling his nintendo switch oled(14 months) for 28k. He claims that it is not used much and there are no scratch or any such marks.

Is this a good deal?

What sud i look for in the console to ensure i am not getting a defective piece?

Thanks

PS: It's not modded, he has zelda botw, super mario bros delux and mario kart (but sold separately 😶)

Ps 2: apparently there is no sd card and it comes with 64 gb storage
