Mouse appearing in good quality, nice rubberized wheel. The clicks are "click": this is normal. Note that this is a mouse 5 buttons and not 3 as I read: the left and the traditional right, plus the 3 buttons in the central scroll wheel: a click in the middle, one in the pushing to the right and a last by pushing left. These allow in certain circumstances, horizontal scrolling in some software like Excel. This may be interesting to some. A software to download the Logitech site, allows to program all the buttons and scrolling, but is not helpful in general in my opinion. Moreover, I give you the approximate dimensions of this mouse that I had not managed to get on the Internet. They are 10.1 x 6 x 3.4 cm. I find a good size. A small downside for me is the length of not adapted to my needs since I wire plugs directly into a USB port on my keyboard: it is 175 cm! (While 45 cm would have been enough for me). One last caveat: the speed of vertical scrolling which even pushed to the maximum, is insufficient to our taste, in any single case with my previous mouse Apple wired white, much more expensive and the small ball serving wheel well is dirty too fast, without being cleaned, the mouse is not removable (like this elsewhere but it will probably be less embarrassing, the wheel is much larger and probably less sensitive to dirt). Altogether product to recommend anyway.
