Today i got my new mouse. A Razer Copperhead. After hearing so many good things about razer i decided to buy one. I thought it would be a great improvement over my Logitech MX510 mouse. Well, i thought wrong. Have never seen a mouse that is so poorly designed and has such crappy materials used as this one. It is the most flimsy thing i ever used. My points of criticism: 1: Poor build quality. 2: Buttons feel like crap 3: Needs more weight. 4: Package looks better then the mouse 5: The seams between the two buttons on top are way to big. So after a while the mouse gets filled with dust and other crap. 6: You have to buy a upgrade kit to add weights. This was my rant about the Razer Copperhead. What a shitty mouse.
