6 Soundmoovz Muzical Bandz

£49.99 for a pack of 2; ages 8+ App required

These bands attach to your wrists or ankles and, once connected to the app, they make different sounds to correspond with the way you move. The bands encourage an interest in music and physical activity, but some found the app a bit tricky to figure out. Great for groups, so children can dance with their friends Bands were fiddly to attach without adult help
