The keys have a pleasant and tactile feedback. I, among others my thesis written and so can not complain!
The function keys are useful, especially Volume / Mute I use often.
Also with the mouse, I am satisfied. At first you have to get used to something the size of the mouse itself. Previously I had for years a Logitech Dual Optical mouseman and was significantly larger. Because the entire hand was on the mouse. In this mouse, the hand rests mainly on the table and only the fingers are loose on the keys. I feel, however, after a short, not to be annoying.
Desperately, I would almost on battery replacement mouse, which was necessary after about 4 months. The instructions I had of course not been abolished and the small cutout on top of the mouse simply invited always "push in" to a. Unfortunately read yourself, do not press with a pointed screwdriver / knife there and the lid would not be solved easily. The solution was much more obvious: Just the back of the "mouse surface" backwards towards palm, push and go!
There is no deduction but that was personal inability ;-)
