The Razer Deathadder is 1800 DPI Infrared 3G mouse. I found out Infrared is a form of optical mouse. Ive been using laser mouses for quite some time now. I want to try an optical again, so this mouse is perfect, I just picked it up from bestbuy for 44.99 on my lunch break. Playing with it here at work right now. Its bigger then any razer mouse I have ever used before. I actualy like its size. The blue light on it kinda fades in and out, which is pretty kool. The scroll wheel is like a rubbery feel to it, and it clicks so thats kool. I just wisht he scroll wheel was 4 way, but what ever. The top of it is a a sweat resistant plastic, but unfortunately the bottom is like the original G7 and has sticky plastic like most cell phones or a PSP.
Im using it on my work PC, right now so like I cant install drivers or anything, but all in all it seems smooth. I cant wait to get it home and play some UT2004 and COD4.
