Thomann 12H Ocarina C3 dark blue

Probably a skill issue, but this one is way harder to play than my ceramic ocarina. The breath curve is very steep, so to play the high C in tune you have to blow hard enough to rival a typical train horn in terms of volume. The highest three notes are also quite finicky, prone to toneless squeaking if you don't get the breath pressure just right. It took me way longer to produce anything resembling music from this model than from my ceramic one. You can probably compensate if you're a wind instrument veteran, but if you're just a guitar/piano person casually trying to get some soothing melodies out of an ocarina, I think you're better off spending €15~20 more for a nice ceramic model.

The build quality is rock solid though. It feels like I could use it as a literal carpentry hammer without breaking it. It's quite hefty and feels much more like a proper instrument than you'd expect from the pictures.
