Review on Razer Basilisk Ultimate Hyperspeed Wireless Gaming Mouse with Charging Dock: Fastest Gaming Mouse Switch - 20K DPI Optical Sensor - Chroma RGB - 11 Programmable Buttons - 100 Hour Battery - Classic Black by Elias Inmune Alv ᠌

In general, for 4k it’s quite a working option, although not ideal Its pros: - Excellent sensor - Fits comfortably in the hand (thumb rest and slight slope to the right really adds to the comfort) - long enough to run on 1 battery, you can buy a couple of batteries and not bathe - In games in the radio channel mode, no delays were detected Has cons: - The main drawback for me is the disgusting work on Bluetooth LE. The cursor moves simply with prohibitive lags that make it difficult to just sit in the browser. (The transmitter is located 40 cm from the mouse) - As many have already written, the buttons are loud, and the left one has a small and not critical backlash. - With a palm grip, my palm immediately starts to sweat, so if you hold the mouse with a claw grip, first try it in a store (4frag for example).
