This is a fantastic little thing! Sounds almost like a theremin on the highest octave, but easier to play. Not easy to play in tune must be said of course. The feature to connect an iPhone via the audiocable is a nice one, just be sure the settings in your chosen app is incoming audio, this is not midi. An auto tune app is a nice option if you want it easy to play. Be aware though that there is only instructions in japanese, but it was not that hard to understand the features.
