But now the great disillusionment: The new series (indicated by the Windows key in Windows 8 look) has become high fledged trash. The keyboard has lost its stability and swings now while typing with noticeably. In addition, rattling keys other than the ones you tap straight. Often times are the keyboard then a "drrrrrrrrr" sound by itself (especially with large keys such as the Enter key). Absolutely no comparison to vohergehenden series.
Why the black version no longer has a matte finish, but a clear coat surface, do not open up to me with the best will. Every touch leaves immediately its mark.
The two stars are there only because of the ingenious unified performance from Logitech, with which several devices can be connected to a common, small receivers and because really, the batteries for a long time. So far I've only after about 18 months the batteries to the mice (M325) must be replaced.
