88 piano keys, audio connectors (2 jacks 3.5) and MIDI bank's interesting but limited in terms of quality: this product is not a piano and a synthesizer.
Pleasant feel, close to the feel of a piano and satisfied the majority of users. But do not expect either to total perfection.
In terms of manual / setup / use RAS
Rather tour for acoustic music / classical. The keyboard responds very well, the pedals will sometimes show a little noisy. The piano sounds are convincing and E.piano. Other (bass, strings, percussion, effects ,...) are disappointing but that's not what you expect when buying such products.
Used almost daily since June 2011 (4 months): no hidden defect!
It is ideal for my use as a substitute for a real piano for pleasure and as a supplement to my amateur studio (used for piano or keyboard sounds "realistic")
Pleasant to the touch, refined design, quality, honest: I hope to keep for many years.
The price is suitable, neither more nor less.
