Pros:
* Sturdy plastic build - can be dropped or thrown into a bag without fear of shattering, unlike clay ocarinas. I found mine quite comfortable to hold and play, as someone with medium-sized hands.
* Very affordable for a starter ocarina.
* Good tuning - avoid those cheap Ocarina of Time ocarinas you usually see online at all costs, They tend to be very badly-tuned, which should be an absolute deal-breaker for everyone, given ocarinas aren't made to be tuned by the player, like guitars.
* Useful booklet - teaches all the basics of playing as well as fingerings for multiple pieces.
Cons:
* Moisture - plastic ocarinas condense some of the water vapour in one's breath during playing. This causes the tone to become weak and muddy eventually, requiring one to quite literally suck the water out to fix it. Clay ocarinas are porous and so do not have this problem.
* Cheap string - Mine unraveled quite easily, but the string can be replaced for almost no cost.
* Acute bending - this is a technique where one tilts their head right down when playing high notes, making them much clearer-sounding. Some ocarinas don't require this technique to sound clear, but this ocarina does.
Overall, I think the pros far outweigh the cons with this instrument, for a beginner especially. I highly recommend it for anyone looking to get started with ocarinas.
