We reviewed the Basilisk Ultimate a while back, but it’s still the number one gaming mouse that I use. The Basilisk Ultimate sports a slick, black shell dazzled with Razer’s Chroma RGB lighting. At 4.6 x 2.79 x 1.49 inches and 107 grams (3.77 ounces), the Basilisk Ultimate is a good size and weight for my hands while working and gaming. With the Razer Focus+ optical sensor, the Basilisk Ultimate also has smart tracking (calibrates the sensor depending on the surface the mouse is on), asymmetric liftoff (enables different liftoff presetting) and motion sync (improves sensor responsiveness). According to Razer, the sensor has a 99.6% resolution accuracy and a tracking speed of 650 inches per second (IPS). When I tested it at the time I queued up arcade mode in Doom and destroyed demons like nobody’s business, from nailing precise headshots with my pistol, to fluently mashing the multifunction paddle to melee and executing some fools. Every mouse should have a paddle in addition to the two buttons on the left-hand side like the Basilisk Ultimate does.
