Startone FP-90 Folding Piano

I bought this foldable piano for 3 reasons: I needed a 88 keys keyboard since I had only a 57, it's foldable, which is great to carry around to anywhere, and has a battery, so I can play it when there is no power source. All those reasons were satisfied, since it is REALLY pratical to use. The fold is a bit notorious when playing, but it doesn't bother.
What really downgrades this piano is it's sound. Well... the speakers are loud, like very loud, but the sound quality of the voices is terrible. If you are going to use it as a MIDI this is not a problem, but if not, it might trouble you. If you connect a good speaker to the piano it gets better, but not much...
