Excellent piano keyboard. I have not yet found a way to become accustomed to the wheel.
. As a consequence of this, the wheel is now used to control the volume, and the other features are more difficult to access.
Pros
design
Cons
After two years, the SHIFT key has lost some of its effectiveness.
Has some pros:
auto turn on backlight when hands approach. comfortable key travel. a separate key on the desktop lock
Has cons:
battery life is not that long. The F-keys are not where they should be, this has already been written about.
