Ordered a Friday around 16h, Received Saturday, the next day, about 12 am, exactly the time indicated. Packaging in good condition and really powerful mouse. I was afraid that the "copper" in fact be as plastic but we feel that this is metal! 4 mouse sensitivity modes, each corresponding to a color LED is working. The supplied CD contains the software required to programming and customizing your mouse in its detail! I'm really satisfied with my purchase! I counsel those who spend much time on the computer to play without wanting to either ruined !! Very good buy!
