Absolute favorite mouse

I have worked for 1 1/2 years with this mouse, it is great in the hand, glides well - still - on many surfaces. Most of all I love the scroll wheel, it is fast and accurate, very smooth and barely audible.
She is still handsome, no disturbing fingerprints, perhaps because the area is not large and is grade despite the glossy surface and in blue what color has a metallic effect. The bright stripe on the side are still light, not stained or soiled.
This mouse I would buy again.
