RAZERTM VIPER 8KHz Get a new level of full control with Razer Viper 8KHz HyperPoling. This two-handed symmetrical e-sport mouse with probe frequency 8000 Hz provides the highest speed and lowest level of delays in history. This model is equipped with the RazerTM 2nd optical switches. generation, that's why you're going to meet every challenge and do your best. RazerTM HyperPolling Technology 8000 Hz Thanks to the actual probe frequency 8000 Hz, the mouse can report to the computer its location and click up to 8000 times per second. This ensures a virtually zero level of delays and speed that has not yet been achieved. RazerTM Focus+ 20K DPI optical sensor With new, intelligent functions such as motion synchronization and asymmetric cutout, the sensor smoothly tracks mouse motion without spin-outs and allows accurate response and precision about the pixel. RazerTM 2nd generation optical mouse switch Increased probe frequency maximizes button capabilities. Thanks to this, they register commands 8 times faster and ensure fast, seamless execution. They withstand up to 70 million clicks and protect against unintended double clicks. Light 71-gram construction The design of this mouse is characterized by uncompromising strength, and a neat format allows easy maneuvering, making the mouse seem a natural extension of the hand. Advanced Embedded Memory The mouse memory houses up to 5 saved profiles with optimal key and macro bindings and Razer Hypershift features that double the button capabilities. This way, you can fight anywhere. RazerTM Speedflex cable The braid used increases flexibility and has minimal resistance, so you can make faster and smoother movements, gaining more control over the mouse. RazerTM Focus+ 20K optical sensor This market-precise 99.6% resolution sensor distinguishes itself with a probe frequency of 8000 Hz — which means a reaction at 0.125 μsms, or almost zero delay of the input signal. Parameters such as tracking, distance of separation and landing, can also be calibrated against a particular working surface, ensuring smoothness of aiming during fast and wide movements.
