Just received this through the post, and i have to say that im quite impressed with it so far. Once the USB receiver is plugged in it only takes seconds to install and start working, the USB receiver is great as its so small that it can stay in your laptop and takes up no space.
The mouse itself is good, looks great with a shiny black top and buttons, slick red stripes down the side. I have quite large hands and it doesn't feel too small, fits comfortably. Only issue would be that with the two AA batteries fitted its quite heavy, but it does feel solid.
Overall a great mouse for the price.
