Korg XE20 Italian Concert Grand Piano Sound

As someone who has been playing piano since I was four years old, I am always happy to find a keyboard with realistic piano sounds and weighted piano keys. The Korg XE20 is such a keyboard. With 88 weighted piano keys, playing this keyboard is exactly like playing a piano. Also, there are two excellent concert grand piano sounds. This video features the Italian concert grand piano sound.

Nice playing. Any issues with the keys so far? some reported clicking noise or stuck keys? Any cons you note so far? Thank you!
