The keyboard is not only a "technical specialties" she convinces in daily use. Apart from that, it is an eye-catcher on the desk.
The keyboard is by its relatively high weight firmly on the desk. 6 rubber feet on the bottom prevent slipping. If necessary, they can be set at an angle.
The stop of the keys is short and hard. But exactly what I was looking for.
With regard to the "power" I had so far no problems. The status display has never been less than 100 percent! Even in completely dark room, with a desk lamp, enough energy is still included.
Great Thing.
The driver installation went smoothly (Windows 7). I already had a Logitech mouse with current Setpoint drivers in operation, and the keyboard has itself integrated into the driver. So it must be.
The "Solar-app", which indicates the charge status by pressing, has been downloaded and installed automatically.
I have not regretted the purchase and speak from a strong buy recommendation.
Update 07/13/2013
The keyboard is now about two and a half years with me in constant use.
Apart from occasional updates of the Logitech software and occasional dusting there is nothing to report.
The keyboard still works as the first day.
A first class product and still be recommended without qualification.
