I must start out with saying I am not an Ocarina player or expert so I will just write what I as a novice thought about this product.
It doesn't cost all that much and it comes in a box with beginners instructions book, so very well packeged.
Feels alright to play, not as easy as a wooden or clay though.
Sound, it does make sound but again one made of clay sounds darker and more mellow.
I'm not entirely satisfied with how it sounds but I can't complain to much since you get what you pay for, and in this case you get rather alot.
There is always a use for pipes and such so I don't feel this as a wasted buy at all, but I will keep my eye out for a clay one from now on.
