This mouse is quite large and heavy, however, bigger is better and it fits in your hand and the weight does not matter (it is still not the door). Many interesting features, especially the left-right wheel and the associated click-zooming roulette. Ditto for the change of application with a click of the thumb side. For cons, I do not see the point of choosing the free movement of this wheel: nothing is gained by running accuracy. Good point for very low power consumption; it is not even necessary to remove the beast with the embedded switch. Also good point for the highly sensitive nano-receiver which is just over the USB port. Overall, a very useful and recommend purchase for office use.
