2 and a half octaves keyboard
souflerie house, otherwise same principle as a melodica (everyone knows ...)
connectors? MIDI and USB (not kidding!)
controllers? no ... Oh yes, a zipper to control the volume! (Yes or it will deposit too, kidding again)
SOUND!
polyphony? Total!

UTILIZATION

Use, um ... music?

SOUNDS

The sound is typed melodica, and less beautiful and less playable
and more souflerie means almost as much as the sound itself!

OVERALL OPINION

Honestly, I have two because I am fan of flea markets and other Emmaeus, or they were 3 times for nothing, but frankly it will never be worth a melodica, be it for the sound, much more beautiful is velvety in the melodica , expressiveness (the real blow is better ...) or the keyboard (and yes, even the keys are more square ...)
for cons, yes it is cute, and a bedside table is nice, but frankly, mugs quickly a melodica, whatever the model, if you are interested in this type of sound
to advise the rigor with asthma who can not breathe ...
