Razer Basilisk Ultimate Hyperspeed Wireless Gaming Mouse Mice FOCUS+ Optical Sensor 20000 DPI Chroma Lighting 11 Programmable Buttons 100 Hr Battery The Razer Basilisk Ultimate is a high-performance wireless gaming mouse that can be tuned to look, play and feel exactly the way you want. Boasting the most advanced optical sensor in the world and armed with features such as a dial for customizing scroll wheel resistance.  Features: Hyperspeed Wireless Technology. 25% faster than any other wireless technology available, you won’t even realize that you’re gaming with a wireless mouse due to its high-speed transmission, lowest click latency, and seamless frequency switching in the noisiest, data-saturated environments, bringing together extreme low-latency and interference reduction for true wireless freedom. FOCUS+ Optical Sensor. Our new, improved sensor has an industry-leading 20,000 DPI with 99.6% resolution accuracy, ensuring that even the finest movement from this wireless mouse is tracked with consistency. Equipped with intelligent functions, the sensor becomes even more accurate, allowing for an acute level of precision for game-winning headshot. Asymmetric Cut-off. On top of the sensor's lift-off distance, you can add another level of precision by using Asymmetric Cut-off to set its landing distance—the distance at which the mouse resumes tracking again. Ideally, you'd want this to be as low as possible so that less cursor drift occurs as your mouse touches the surface. 11 Programmable Buttons. Have a greater arsenal of commands at your fingertips by mapping your favorite macros and secondary functions via Razer Synapse 3. Like its wired variant, the Razer Basilisk Ultimate includes the signature multi-function paddle. 14 Customizable Chroma Lighting Zones. Each lighting zone on this wireless mouse can be individually programmed in Chroma Studio, making it a standout addition to your battlestation as you light up your opponents. Customizable Scroll Wheel Resistance. The Razer Basilisk Ultimate comes with a dial on its underside that lets you tweak the resistance of its scroll wheel to be as smooth or as tactile as you want. With this level of personalization, you’ll be able to more accurately perform bunny hops, weapon selects, and other scroll wheel actions. Mouse Dock & 100% PTFE Mouse Feet.
