Review on HyperX Pulsefire Core RGB Gaming Mouse - Software Controlled Light Effects, Macro Customization, Pixart 3327 Sensor up to 6,200DPI, 7 Programmable Buttons, Lightweight 87g by Ba Li ᠌

With its pros: Fits comfortably in the hand. Nothing creaks and does not play. The response is good. Some cons: Of course, not quite a disadvantage, but it delivers extreme discomfort. By default, the side buttons are "mixed" with respect to most mice. It's about the m4 and m5 keys.
