Sensei Wireless uses the latest in wireless technology to deliver exactly the same performance of our wired Sensei tournament-grade mouse. We equipped the mouse with the highest polling rate on the market (1000 Hz), delivering a 1ms response time that eliminates wireless lag. We use a high-speed, proprietary 2.4 GHz wireless solution that is optimized for extremely high data throughput & allows for incredibly low latency. in addition the Pixart ADNS 9800 laser sensor means that you can ramp up the CPI to 8200. Sensei Wireless was refined from the ground up to make it a stunning addition to your gaming setup. Ergonomics, metal & illumination blend together in a mouse that looks as sharp as it performs.
