This mouse is great!
Pros;
The receiver is quite small. It only protrudes about 3/8" from the USB port.
The scroll wheel has two modes, first is the standard click as you scroll, second is hyper scroll. By pressing on the wheel, the click is disengaged and you can spin the wheel with a flick of your finger and scroll up or down faster than you thought possible. I use hyper scroll 99.9% of the time.
There is also a back and a forward button on the mouse so you don't have mouse up to the top left of the page to click on those functions.
Cons;
None.
