Melodica : Great for parties, relaxing, acoustic jams

This is an entry level instrument, and while I would not bother to incorporate it into serious concerts, I have jammed with this in parties, played along songs, and performed on the streets with it (with acoustic guitar as rhythm section).

Pros: the price meets and exceeds the function. It comes with both the short mouthpiece and the extended pipe. There was a handy semi-hard case as well, never used anything else. The sound is a bit harsh (harder than accordion), but is tuned quite well and has stayed in tune.

Cons: cleaning after intense usage is hard. Even with the vent button, I've had to undo the screws to clean it completely. Build quality is basic, which is what you would expect for this price.
