HyperX's Pulsefire is a mouse, plain and simple.  It does not glow, nor can you remove or add peices to it, it is just a large, functional $50 gaming mouse with a Pixart PMW3310 optical sensor. The Tech Report tested it out, contrasting it to the Logitech G302 which the reviewer uses on a regular basis.  Take a look if you are shopping for a mouse, and only a mouse, not programmable macro, weight enhanced and sensor swapping input device of doom.

"HyperX is making a foray into yet-unexplored gaming peripheral territory today with its Pulsefire gaming mouse, a simple and software-free rodent. We put this mouse to the mat to see whether HyperX's keep-it-simple approach plays well with gaming mice."
