Zalman showed us its new ZM-GM4, an 8200 dpi gaming mouse with 8 customizable buttons and adjustable weight and dimensions.
It includes the hex key necessary to adjust the mouse. The bubble on the top is where the weights are, just like in the ZM-GM3, the predecessor of this unit.
In our initial feel, the position of the buttons is likely to be a little weird at first, but may be useful as the user becomes accustomed to it. A big silver lever button is perfect for some infrequent, calculated action, like an alpha strike in Mechwarrior Online.
The ZM-GM4 will be available in the first quarter for $75.
