A pin takes up quite a bit of space for dorm living. Double check that there’s a good space for a machine before you show up with one. Imagine if each kid wanted bring a pin, would there be room in the house?
I think it’s great that you want to give your son a pin while he’s away, but I don’t know if if it’s the right time/place in his life for that. Wait 5 years until he has his own place and graduated. Less concern for keeping the game safe.
