Just bought one of these for my 8 year old for Christmas.
Was mulling over the switch but managed to pick it up in great condition with 3 wiimotes, the main handheld screen, Splatoon, Mario Kart 8, Wii Party U, Nintendoland, Lego Marvel and Smash all for £100.
Going to get Mario 3D Land.
We borrowed the switch for a weekend but the controls were quote fiddly, so though this would be ideal to introduce him to Nintendo and get him away from Fortnite/Minecraft for 10 minutes
