Peripherals are mandatory when making a PC, and while many people don't fret about their mouse, gamers, especially those who like shooters, usually choose their mouse carefully.
Knowing this, Genius made the NS-6015, which combines the benefits of a 1000 Dpi optical engine with the Bi-directional 2.4 GHz anti-interference technology. This ensures that the mouse communicates accurately over the air with whatever system it is installed on, provided the distance is of no more than 10 meters / 30-33 feet.
An AA battery powers the mouse for up to 10 months, and AAA batteries can be used as well. There is even a power switch that can preserve energy.
Genius is already selling the NS-6015, in Metallic Red, Blue or Sky Blue, for $12.9 / €10 – 12.9. It doesn't matter what the dominant hand is.
