We use mighty as a screen-less mp3 player for our son with autism. He loves it and we do too!
Very happy to have a good spotify player without a screen for children, juste have to be patient during the synchronisation process.
Good product
This is our second mighty. We are really happy with it as it gives our kids independence to choose their own music and stories and not need to rely on us or a phone to access it. Obviously it does involve adult updates and phone admin to add music etc but it is definitely much nicer to not have to get the phone out every time! Easy to use, robust and great capacity.
