Keyboard used to, not for everyone!

I have now tested the keyboard for 3 weeks.
My Conclusion: One of the best "gaming" keyboard which there are currently on the market!
Among the keys:
They are obviously difficult to use at first sight, and "pressure", they have an unusual shape of the keys (W, A, S, D, G1-G9, arrow keys are provided with an even extra-deep "trough") have all keys these depressions form (unfortunately do not know better that to describe), characterized the tap is press the keys first very unusual.
The buttons are very "difficult" to press, maybe it is indeed by my predecessor my sponsor Roccat (Roccat Isku Multicolor). Both were, however, mechanically allows the Logitech Orion Spark push much harder. That does not make them truly Office-compatible / friendly ... write longer I personally find as torture!
However, personally I need the feedback from the keyboard that I ever press a key, sometimes happened to me in my old keyboard that I was wondering if I've ever pressed a button that I do not have now. I know exactly where, when and how which I have pressed. Otherwise I reach all the buttons I need very good and easy. But is in the hands of the viewer, what game genre because he / she is playing and how big his hands are.

Appearance
Box not as big as expected. Inner box kept simple as all the new Logitech series.
I was first surprised how small the keyboard but since I have otherwise tested other monsters btw. had owned.
As I said, these keys are hard to miss. Even without lighting they are very strikingly different.
Simple design. All plastic. 1 piano black element otherwise kept all matte black plastic. Can you see negative or positive. To each his own.
For me personally it is completely no matter whether a "quality" Corsair with Alu elements or not.
Does it work? YES!
In the Logitech own program "Logitech Gaming Software" version 8.57.145 (I currently have) is detected, the keyboard and you can still install / adjust feature.

Lighting: (personally big topic!)
When other elements of Logitech as mouse or gaming pad detects the software.
I come to the part of major points.
In the 3rd rider of the program you will find the lighting settings. Since you can choose between lighting Monochromatic, zone, to Commands, effect.
What that means?
Monochrome: an infinite number of colors from the color palette, you can choose in all the keyboard lights up.
Zones: Preset "zones" the "normal" every gamer used lights, but you can in the Zone lighting option itself still select keys to the well lit, by clicking on them.
The personal best!
The command lighting: The Logitech Gaming Software reads the commands from the respective game and highlights these separately. This means. Counter Strike: Global Offensive / Battlefield 4: the W, A, S, D, 1-9 buttons are illuminated and those which you have assigned in the settings. "Automatic readout"!
This mode "command lighting is automatically activated once the game starts, however, not only the keyboard but the mouse, keyboard and game pad are adapted to the respective game.
The games recognition is unfortunately limited to very few current games.

The lighting effects:
Self-explanatory.
there are breathing effect, star effect, color cycle, color wave, press (it is the illuminated button that was pressed last)

Positives:
+ New concept
+ No screen (personal feeling that a screen on the keyboard is useless)
+ Buttons shape
+ Keys Feedback
+ Anti-Ghosting
+ Illumination

Negative
-Price
-Plastikverarbeitung (Because one's personal opinion)
-harter feedback of keys
-schweres press the keys

Logitech has put an exclamation point in my opinion!
They have created a PURE Gaming Keyboard.
No frills (G19-color screen, no one need a monitor to the keyboard while gambling)
It is not made for Bürotipseln. REIN for long press on it as FPS or quick key commands such as Starcraft II and League of Legends, Dota 2 is made it. NO office work!
I have "pain" on his fingers from typing this review with the keyboard, feel even as build muscle, because you can push so hard.
The keyboard is purely for gaming.
A hybrid like other keyboards it is not, unfortunately, in my opinion.

Experience after 4 weeks of intense season * 16hrs a day
