I am playing very basic stuff on the harp and I must say I bought this as a toy. First, my mistake probably for not reading the details, but I was taken aback by the size. Including the box, it is not bigger than half your thumb. Second, I was then surprised by the sound: fairly loud and really clear: so it is not a toy, I guess you could use it seriously to surprise people in a gig for a few minutes. And don't give it to kids, they might swallow it ;) Honestly, a very good surprise.
