u/galaxyrocker and u/halpadultingplz - the Night by Noble and STL plastics are great. The Focalink plastic is great too. Some Amazon reviews are really questionable. This ocarina is universally known to be a paper weight by anyone with any sort of experience at all with the ocarina, yet it has nearly 2k reviews - and almost 5 stars.It's insane. I have no idea why they have so many positives. I suspect people aren't experienced enough to know how bad they are.
Of course, some ocarinas provide a better value than others, but the three listed above are solid, though the Night by Noble keeps going up and up in price and becomes less and less of a value proposition and more of a "durable and really really good ocarina' proposition...
