The distortion was poor; however I have noticed that a lot of phones do that when recording music, (There only designed for the narrow voice range) so it may not be the keyboard.

Why anybody makes a judgment of a keyboard with a phone recording (See above) escapes me.

Keyboards are usually voiced differently for the Asian (As in the video) and Western market so again there is no idea of whether this is anything like what a western version will sound like.

As I have always said (Similar to what Bachus said) online demos are a waste of time in trying to judge what a keyboard sounds like, the only way to know for sure is to try one for yourself.
