The shape is almost perfect, and if one is destabilized at the beginning, one hour is used to. The huge cushion allows to rest his wrists while typing. The mouse is less successful but very nice nonetheless. However, this package is not designed for gaming: you can play with, but it will not be as good as a whole keyboard and mouse gamer.
I particularly appreciate the separate numeric keypad, my favorite place to the left. My only regrets are no lights for caps lock and batteries. Moreover, it is not backlit, and mouse lacking some additional features (only a "Start" button for Windows 8 and a back button on the left side).
