I just dont get why people like the MX series mice. I find them extremely uncomfortable, especially around the thumb area as my thumb doesn’t fit the contour of the groove at all. The buttons around the wheel are too awkward to use, as are the thumb buttons, and the rest of the mouse is just clunky and horrible.
What exactly is the point in a free moving wheel and since when does having something that spins freely for 6 seconds aide 'fast weapon changes'? That and logitech seem to be obsessively going for wireless designs which completely negates the point in a gaming mouse.
The Razer Copperhead is a far better, smoother and comfier mouse of the price
