Mouse very well, middle mouse button not optimal

Bin with the mouse that I use on the notebook, very satisfied in its entirety,. It is very simple and it is me well in hand. Of course, it is not super-ergonomic, but perfectly OK for this price. The USB receiver does not interfere with and is very powerful.

The only downside (which is why "only" 4 stars), the middle mouse button, so the wheel for scrolling, "running" too quick for me. It has too little for my tastes resistance. Even the Press, eg to open a link in a new tab in the browser, does not always work, because the wheel is a bit shaky easy.

Who the small drawback does not disturb can access safely, a top mouse.
