The plastic in this ocarina feels sturdy and premium.
The included guide with notes and song excercises is a real gem; I've had a lot fun learning to play it.
It handles good, but I cannot judge the sound since this is the only ocarina I've played to date.
It's a bit loud when you go on the higher notes, but I guess that is how it is with this kind of instrument in general.
For this price, this is a no brainer; just buy it and try it.
