This keyboard is very nice, although a bit large (we'll see if I get used) keys on a system for detecting a single pressure or continuous pressing keys. (I do not know if we can turn it off, personally I find it annoying) There is the possibility to find addons for keyboard screen (little but it's something). Otherwise it seems solid, the audio jacks are of very good quality. The macro system is effective.
EDIT: I removed even star because the audio output (which is why I bought it) bug in a short time and made redémarer keyboard. whereby the game sound section and it is unusable for 1 to 3 seconds. Restore the sound must restart the game ...
