I previously owned two alto ocarinas, the Focalink Plastic AC and Double AC.
First of all, this Ocarina is huge compared to those. My hands are quite small and I sometimes struggle with switching between the holes on the left side (when playing fast), however it is not a problem for slower melodies.
I do not find it cumbersome to hold in terms of weight. The fingering can however get a bit awkward, as mentioned above.
It uses Asian fingering, meaning that the pinky on the left side is lifted after the thumb. This is necessary for balance, but also made the transition easier for me coming from two Asian ocarinas.
The sound is very deep and resonant. It even vibrated a bit in my teeth the first time I played it. It uses a rising breath pressure, meaning that you blow harder as you go up the scale. By underblowing the first hole, a B can be played quite easily. The first hole is also divided into subholes, making it easier to play sharps/flats.
Being a clay ocarina it does not have condensation issues, but you might want to get a cord for it so that you do not drop it in the floor and break it.
It comes with a triangular protective case, which was a nice touch.
