I can express only positive about this product! It's my first digital piano with weighted keys! So we come before only one of the most important aspects: The keyboard. The keyboard is a true masterpiece for an instrument in this price range! The GH (Graded Hammer) keyboard is indeed one level below the built-in Clavinova CLP 480 GH3 keyboard, which is not particularly makes itself felt! Now we come to design. The design has been kept lean and minimalist, which I personally very ascribes! The only tiny point of not precipitated is in the Service. ;
