Excellent laser mouse I have for 3 years and still hold a long time I think despite the number of hours of game she had. You can really set the mouse as we want between sensitivity, feel and comfort of use. The weight given to allow them to be really comfortable and the buttons are well placed (to me anyway). Possibility to set the sensitivity directly on the side of the mouse, the laser is precise even in max sensitivity. A button lets you choose the color from blue, turquoise, red, purple and green. The color indicating the sensitivity level does not change against. Basically mice convenient, comfortable, good quality that I recommend.
