It's hard to explain, but the mouse feels rubberised and the shape is very comfortable to hold. Even if you don't have giant hands, the side buttons are easily in reach of your thumb. Underneath, care has been taken to make sure the feet don't wear out too quickly, or collect dirt, and the mouse glides effortlessly across the mouse mat. The scroll wheel appears to be made of metal with a rubber surface and can be set to free-wheeling or incremental movement. Free-wheeling is brilliant for scrolling through long lists or web-pages, although obviously less appropriate for gaming. There is a button on the mouse to adjust the cursor travel speed and together with the alien's head logo, the indicator lights can be made to glow different colours, for which there is a desktop app. Although badged as an Alienware mouse, it is apparently a Logitech design. I really can't recommend it highly enough.
