TweakTown posted a review on the Bloody SP80 Bleeding Edge Gaming Mouse
A quote from the article:
The whole point of LK switches is to remove the mechanical failure points in switches by removing the guts of a standard mechanical switch, and using a beam of light to be broken to constitute actuation of said switch. In doing so, not only does it help with longevity, but the actuations are more precise, travel does not have to be as long, and with the technology in hand at Bloody, why not try to do the same thing with mouse switches.Bloody SP80 Bleeding Edge Gaming Mouse Review
While many peripherals, especially mice, tend to be great for a certain subset of games, we have not seen a mouse that offers software which is geared to each subset. Meaning that of you like FPS titles, there is a section for that, you like RPGs, Bloody has a section for that too.
