I now own for several months, and I have to say it really is a joy to touch it.
The manuals supplied with the software is very useful and also not hard to understand. It works with Windows tadelos. 7
Useful, for example, that you can turn the FN key by the software as a permanent activated so that the function keys work without zusaätzlichen keystroke.
The keys are very flat, like a notebook keyboard, which I personally liked a lot, but is certainly a matter of taste.
Visually it looks very appealing, a small strip of piano finish adorns the keyboard LEDs are being used in the right pane, for example, the NUM activation etc See, in the same color as the LED buttons.
The lighting can be adjusted in 4 steps: off, low, medium, light.
The luminosity I find quite impressive, on the bright stage, the keys are also conspicuous in daylight. A special eyecatcher is the keyboard of course, in the dark.
The function keys (F1-12) and pressure and Pause lights in orange and therefore provide good landmarks.
Furthermore, the typing speed is subjective definitely much faster, because the key pressure point is so good and precise set.
Conclusion: Very great part what Logitech conjured up because it indicates that the usual quality has also been introduced in this keyboard.
Everyone standing on slim, fast and visually appealing keyboards should, through an acquisition illuminated think of, the price is not a bargain, but she is all worth it!
