I am very happy with the performance and finishing in very solid gum but the worry is that it did not last long! indeed barely three months then impossible to obtain recognition by windows 7 xp so I gave it a shot on the site [...] (all in English), which proposes an exchange because this model is guaranteed and my 10 YEARS surprise I received a new key 16GB instead of 8 and usb3 SUPER !!! CORSAIR THANK hoping that this one will last longer ...........
