This mouse requires some time to adapt to the level of sensitivity (3 levels adjustable via software downloaded from the Corsair website), and, for my part, the weight level also. The three included weight does not make it heavy enough to my mind (matter of taste), but this makes a very good response, however, which is complimented by the very smooth glide. The mouse is nothing superfluous, and the Sniper button, outside its usefulness in the video game, allows for specific actions to DTP for example. Although this is secondary, I find the sober and elegant design, nothing overloaded, and blue lights provide a nice aesthetic side in the dark. The "sheath" cable is also appreciable.
