Just got one for my smartphone-free 10-year-old daughter as a birthday present. I have yet to see her without it - basically wears it and plays music all the time, including family dinner. I'll ask her to stop the latter once the initial excitement cools off, but were it up to her, she'd probably also sleep with it. :)
Works amazing
There is so much space on this player! I absolutely love it! I love that it is waterproof also! My daughter keeps trying to steal it from me!
