Logitech G7 laser cordless mouse

The good: 2,000dpi laser sensor; two rechargeable battery packs; easy-to-change sensitivity settings.

The bad: Lacks removable weights; right-handed use only.

The bottom line: The Logitech G7 Laser Cordless Optical mouse has a 2,000dpi optical sensor, programmable buttons, adjustable sensitivity levels, a quick-swappable battery, and most importantly, no cord. But gamers who don't mind being chained to their computers should consider other, less expensive options.
