Otherwise the keyboard itself is really not bad, I love the effect of the LED between the keys, the design goes well with the rest of my PC all the necessary keys are really a plus: Lower the sound Moving Up Cut, Change color (etc ..) And we have the right to 12 programmable keys and more G1 to G12 for the players and it is really a plus. It also has the right to slide a button to block the writing of the keyboard, not very useful but still worth taking.
In conclusion, very good keyboard but the driver lowers his note, I find it a pity.
