Would have loved to not have lost so many improvisations, and consciously recording every time before you start playing is too much hassle.
With that said, I'm grateful for the mechanical stability of it, and also the reliability of the interface.. Should not be taken for granted. It has buttons, not a touchscreen for example (Kawai digitals were sadly out because of this.)
However, the internal capacity is fairly limited and there's some tolerable yet a delay after the recording to save the buffer on the flash.
I don't think there's a ready way to copy such internal recording from the piano onto some external medium.
This device may be a nice 'upgrade' for such digital pianos. It'd be nice if the recordings can also be played for a selected hand, so that it could be used in learning.
