Excellent mouse with buttons "forward" and "back" to surf faster!

Good grip, good precise optical sensor on almost any surface. Very useful buttons on the left side to surf the Net, thus avoiding clicking on the buttons "Previous" or "After" the browser and lose a lot of time if you have a lot of work ... Very also practices wheel that rotates on its own and lets get down to the bottom of a blog with hundreds of lines. For cons, I would have preferred it to be even lower because there we must go back a little finger and it's slightly disturbing. The cut is done very easily with the little button under the mouse. The contact texture is nice and easy to clean.
