In addition comes to the fact that the keyboard does have the multimedia features, but does not degenerate into a penetrating keys usury - even for the eye a beautiful thing.
The mouse is very comfortable to hold and has a pleasant weight. This ultralight mice I do not like in their hands, because they give me a very uncomfortable feeling of control. The Logitech has done very well here.
Haptic is by the mouse of keyboard slightly, but it does not bother me particularly. Also in this device has been dispensed with unnecessary buttons. 3 buttons, scroll wheel, finished, out ... so I like that.
Bottom line, it is about 50 euros a decent desktop set that very well meets the demands of power users and at your desk makes a good figure.
