Some people consider the software that comes with this device to be a disadvantage. I do not think this is correct, since not all devices have software at all. In principle, you can find a lot of useful functions (16 in 1, changing the polling rate, adjusting the sensitivity modes.). There are paid "macros" with which you can extinguish the impact and make it easier to kill your targets, but, ask yourself, do you need it :) ? The software has both pluses and minuses, but, in general, it simplifies device setup. It is a pity that some settings are lost after restarting the computer or changing the mouse core. But these are the shortcomings of the software, and not the mouse itself. I bought a mouse for 1,390. I am completely satisfied with the purchase, only some elements were not included in the kit (replaceable legs, software disk, etc.). There were no problems with the basic setup of the device using the software either. Carefully read the instructions in the process of working with the software and it will become easier to configure it. Happy using! :)
