For gaming, the C490 4-in-1 package combo was created. This USB multimedia keyboard has 19 anti-ghosting keys and a color backlight. The mouse's design is ergonomic. You can play the game for a long time because the contour design of the appearance fits the curvature of the palm, making it comfortable to hold and easy to use. The 2400DPI high-resolution light sensor can locate targets in the game rapidly, track high-speed data, and react instantly to opponent movements. You can change the mouse's movement speed and see which settings are active at any given time by pressing the DPI change button. The mouse pad features a smooth cloth surface for smooth operation, clear stereo, a high-sensitivity microphone, and comfortable leather earmuffs for an ergonomic design. The bottom is precisely locked and non-slip.
