For years I have used this mouse, 3,000 hours of Arma 3, 700 of DayZ and many many more from other games. When the cable eventually breaks, I will fit a new USB, when the switches turn to mush I will solder in new switches.
I'm far from a fan boy, especially when it comes to Corsair but the Scimitar, best mouse I have had.
That is my (combined) M$ trackball. There are 2 boards in my trackball, 1 for buttons and 1 for the ball, First one the ball board stopped working, the second the button board stopped working, I opened em up, unplugged the top board from the bottom board, put the 2 working parts together and it is still going strong 26 yrs later, even the wheel and buttons only click once
