In my case I bought for "play the piano", so I was not looking for lots of functions. This is a piano that I highly recommend to beginners and experienced pianists who want a digital piano is as close as most of the acoustics. The keys are made of wood with synthetic ivory surface, touch is really perfect, the sound is very round, very clear "with one exception, see below).
Everything is perfect, the feel, the manual is clear and sufficient (complete), the configuration may seem a little complicated at first but you get used very fast!
Touch is really impressive! One would imagine almost on a real piano!
The main sound of the piano Grand Concert is correct. I could have put "perfect" but it is however a problem: at the G-sharp to B flat, the notes are slightly more powerful (and I mean slightly), and are heard fairly compared to others (especially when agreement), we must be very precise when you play those notes.
I use it for two weeks now, and I am fully satisfied! I was looking primarily a piano whose touch is neared to the more acoustic, and it's really this one I needed!
I tried to by before and got information on several models including the Yamaha CLP 430 (which I did not like was the plastic buttons, and the sound too much metal), the Roland HP 503 (I did not appreciate at all the touch), and the Kawai CN-33 (it was really good, only the keyboard HR I did not like too much and the keys were not wood).
In terms of price / quality ratio, I find this great piano! with experience, I think my next choice would be heading more towards the sound.
Only flat keyboard I repeat, this is the sound of B flat to G sharp, which is felt more than other grades, but this is just a detail not too serious (less is heard through headphones).
Very good piano, Kawai I recommend to all! And this piano
