Help with the Melodica: Musicians' Input Appreciated


So I’m going to buy a Melodica (as seen in the picture) and I had a few questions before I begin to learn how to play.

First of all, I would like everyone to know that I do not play any sort of instrument and I don’t know how to read sheet music.

That being said:
[]Is buying a beginner’s piano book a viable option for learning how to play the melodica?
]Can piano sheet music be used to play the melodica?
[]Do you think that the mouthpiece is played like that of a recorder’s mouthpiece?
]Any tips for a beginner to get started with this instrument?
Thanks for any input
