Before purchasing this mouse, I used g305, which after a year of daily use began to double-click. I took the mouse spontaneously, I wanted something unusual, and, having looked through the market, the choice fell on Viper. I have been using the mouse for more than 2 months, it works perfectly. Its only drawback, PERSONALLY FOR ME, was the form. After prolonged use, the hand begins to hurt. But this moment is very individual, so gamers are advised to go to some game store (feel and touch) before buying. I recommend to buy.
