Good gaming mouse at a reasonable price. As for the paid software - you can of course hack, or you can buy an already activated mouse within 1000r. and don't bother with breaking. All the same, analogues from other manufacturers are more expensive than 2 times + unnecessary gadgets - such as replaceable panels, exorbitant dpi values, etc. Here someone also wrote that the backlight was flashing continuously, so the diode had to be pulled out - I did not understand why the person was "tensed up" like that. You can set four levels of backlight through the software, including turning it off completely.
