I made a glowing review when I got it, but I have to see my comm. The keyboard has proved moderately long practice, key programming, I do not even want to talk. And ESPECIALLY after 6 months of life, he just let me go. Completely broke down, no longer recognized windows, more alimenté.Après disassembly, cleaning, it is apparently the chip that handles the keyboard that is dead. I DO NOT RECOMMEND THIS PRODUCT MAINLY that really disappointed me.
