20 times as accurate as the average optical mouse, the MX Laser Engine can detect small movements over surfaces that would get passed by by other mice. Matching the specs of the MX510 gaming mouse, while still using a cordless chassis, the MX1000 is a true gamers mouse. It provides 800 dpi resolution and 5.8 megapixels per second image-processing rate, which hitherto has only been possible with corded mice. Now the same performance is available wireless. The mouse is equipped with a rechargeable battery, and the base station serves double duty as a battery charger. The battery even comes with a three year warranty. All in all, an excellent product.
