This is a wonderfully designed keyboard. Almost perfect. Much more comfortable than a regular one on my wrists and I like the light color of mine though the darker ones look beautiful too. Improvements to me would be a little less button movement, backlighting to make darker hours easier to maneuver, and a better sync with the apple keyboard systems for some shortcuts. But it's still great.
Once the keyboard gets set up it is clear sailing. Took a little while, had to change out four keys for Windows an made sure to use the wireless set up.
It is the best key board I have had in a long time.
