Review for LEGO set 43101-13 Complete Set from maxi-geek.com
“Alongside the main sets will be additional Bandmates minifigs to obtain, though you don’t have to. These each come with one special BeatBit and two random BeatBits. BeatBits are a creative and endlessly combinable system of audio-visual effects. They are lovingly printed,... More like little album covers, on 2x2 tiles representing music effects, character dance moves and scene props that come to life when scanned by the app.”
