An attractive mouse, I chose the red, which matches the rest of my system. The mouse comes with an LED option. The LEDs are attractive, with a lit stripe. I burned through my battery is less than a week, although that was with a standard, carbon zinc battery, not alkaline. Currently I'm testing the mouse's longevity without the LEDs. The battery is easy to change. The mouse enters a sleep mode after x minutes of inactivity. That period is longer than other mice I've owned, so generally, won't get in the way. Click to wake it up again.
The mouse is optical (not laser). Its accuracy seems fine. I'm able to use it on a desk without a mouse pad. There are several levels of adjustable DPI, which is essential in any good mouse. This gives you the mouse-to-cursor movement ratio.
The weight and size of the mouse is excellent, although the battery you insert does add weight to the back of the mouse. The mouse feels very comfortable in my hand, and I would recommend it it based on the hand feel. The buttons are quiet, and comfortable.
