The keyboard has a noble USB cable with 2 plugs (probably one for the keyboard itself, the other for the integrated USB hub). An ugly criticism: If the PC is brought by pressing a key on this keyboard from the power saving mode, it does not recognize the keyboard. Only a reboot fixes this problem. If the PC is brought by pressing the power button from the power saving mode, the keyboard is working properly. Perhaps there is a solution, I have not been looking for it for this problem.
To feel: The buttons are all well made, but I can attest to the keyboard not absolute recommendation. I write in a flowing 10-Fingersytem in which probably some would Sektretärin pale with envy, but I can go to so many 15 Euro keyboard sets to work. But it is not as if the keyboard interfere when writing a novel, I would not write it.
The special keys I have not yet used, but it calms me immensely that I have :-).
Conclusion: If you like glowing keys and plenty of room on your desk has (the Tasatur is very large) will not make much wrong with this product well. The many buttons I could imagine or programs that use a lot of shortcuts (eg Photoshop, flight simulator, etc) Me playing. Who would use the keyboard exclusively for typing long texts, you should look to hire for a copy with mechanical keys. Or those thin laptop even keys that I personally find quite handy.
