makes sound and doesn't break
This can't be tuned or played as a real instrument. You can just make random pitches on it. This was a disappointment as I play guitar and hoped to goof around with it myself. I can say that by 20 months my son hasn't broken it however, not even the strings.
He only pulls it out to play with it about once a week (usually when I'm playing my guitar) and gets bored after a couple minutes. I would not recommend this to anyone.
