The first time I come across the products of this company, I decided to try something new, apparently in vain. Immediately after buying the mouse, I decided to flash it for a newer version in the official software, after which the mouse stopped working. Wrote to technical support in FB, they solved the problem. After another 4 days, a double click appeared, which finally killed my relationship with this mouse. If it is not noticeable in games, then when surfing the browser it is unbearable. 4 stars for the price and good stuffing
