Beautiful design, probably unbeatable price for a gaming keyboard (especially since I myself bought new in refurbished has 20 or 10 less than the official price!), Works perfectly (very good backlight).
But the finish could be better: the 8 blue keys are coated with a glossy paint too thick and with little visible scratches and one of them ("S") has the same letter rather coarsely / dug / in thick layer of paint, which really is not beautiful!
Finally, it is regrettable that the LED indicators for interlockings keys (Shift, Pave 'Defilement and digital) to be arranged around the potentiometer and setting up of the retro-lighting intensity, without any indication of written (we guess of course only in support of the 3 keys of the 3 LEDs corresponds to it - it would eté logical and more intuitive to add information written below the LEDs!).
And finally, pity also that the button toggles between the colors red (original) and blue backlight is precisely the Lock the scroll key !! I imagine that the vast majority of people never uses it, but it is not my case (it often is used in particular to put a game to pause, especially in emulators microphones / console / arcade) and suddenly his dual function is unfortunate, why not have just planned an extra touch dedie'e exclusively tilting color (especially that there is anyway already a button serie "multimedia" extra - that are simply qques shortcuts to key functions such as default browser, calculator, fast forward / rewind, volume up / down, media player, etc. - it would have been easy to add a series of buttons that toggle button a red / blue the backlight instead of assigning this function to an already existing key already having its own function, even though most people do not have utility!).
These imperfections put-a-hand, it's still good anyway claiver, efficiency, aesthetics and imabattable on its quality + functionality / price!
