Something between an instrument and a toy. I would say that the big version (Deluxe) is some playable and with a little practice you can play scales and arpeggios. I've tried before also the original version, deluxe version is definitely more instrument than a toy. Cute design, responds well with mouth opening, also sound output replicates the response on mouth opening.
I used it in some jam session and in some music comedy videos, audience response was crazy!
Build quality is very good, it feels very solid.
