Very poor design of the mouse wheel. At the slightest touch to it during the game (shooters) it changes weapons, and I usually put reloading on it (wheel). It becomes impossible to play. Of course, you can assign another key, but why can a mouse for one and a half thousand perform such functions, but not for 17?! There were problems with the software of this mouse. I could not download the driver from the official site, I tried many times and gave a download error. As a result, I downloaded from the left site. As a result, what with the driver, what without the mouse, or rather, the same ill-fated scrolling (scrolling with the wheel) in some programs, for example, Total Commander works strangely, i. E. when scrolling down, returns the list back to the top (and this is not everywhere, it works fine in the browser). When you try to scroll down the page on the keyboard, it also returns the list up. Perhaps I did not take into account some settings (although I climbed everything in the program for programming this mouse, shoveled the entire Internet and did not find a solution to the problem).
Also, the mouse may stop responding to any movements and keystrokes ("fall off"), only reconnecting the cable in the connector helps.
