It seemed rather cool to have a metal scroll wheel, however its mass slows it down and its cold to the touch. The worst part about it is the spring tension on the wheel button which is about 3 or 4 times the pressure I needed to activate the button on my Razer Death Adder mouse. I use this function a lot in my games and now I am not as quick or accurate in those functions due to the stiff button. The textured side panels actually seem slippery when compared to the smooth sides of my Razer mouse, kind of a surprise but I guess the textured TPU is inherently slippery. They need to find a different material if they expect this to work. On the plus side of things is the fire button located on the side of the mouse at the tip of the thumb, and I can see that becoming useful in some instances. I like the fact that I can adjust the weights and am currently running with three of them. My gripe is that door of the compartment that covers them seems flimsy and could pop off too easily. For now I am switching back to the Razer as there is too much to dislike about the feel of this mouse.
