Canon and works perfectly

I wanted a mouse, discreet, not clumsy, and not too slow for wireless. The operating mode and settings are quick and easy. It is less cumbersome than a wired mouse. I find taking perfect hand and more natural, intuitive than conventional mice. My friends are often perplexed by the absence of the wheel but I got done very quickly. Similarly, the left and right click are not visible but work fine. To return to the previous page, it is instead more subtle and sometimes a little too sensitive since it is necessary to touch the right side of the mouse. Otherwise it is not greedy in stack since I bought it there more than a year without changing batteries, it still does not show signs of fatigue.
