I got this recommended by a friend, he told me "you won't believe it's made of plastic".
He was right, its sound is very close to a good ceramic ocarina. Add indestructibility and a very comfortable rugged texture, and you get exactly what I was looking for: a powerful, well-sounding ocarina that I can take everywhere without fear.
It is a bit on the breathier side, but one gets used to it pretty quickly.
