I have to agree with Valantar, it's a carbon fiber look and would fit the overall 'racing' theme. Obviously not real CF given the relatively low cost, genuine CF is rather costly. So long as the mouse holds up, for what it offers $40 isn't too bad of a price.
I'm also thinking it's Carbon Fibre but I also think think it's not Faux Carbon Fibre...well I've got to see this mouse up close. EVGA's X10 Carbon is really light weight and not just some plastic knock with Carbon Fibre applique on it.
A lot of companies are designing around this style. I have the Gigabyte M7
Thor that has essentially the same frame design and button lay out minus the cf look that I picked up for 29.99 to use in my office. I'll definitely be taking a look at these products if they show up on the local Frys/Microcenter shelves.
I recently just picked up a Razer Ouroboros. The main reason i chose this mouse is because you get to weight tuning it. Being a gamer i think that is extremely important. Since i purchased this mouse it has been nothing but great to me. Check out .
