What's better than 18 buttons on a gaming mouse? 19 buttons on a gaming mouse. That's how many Razer boasts on its new Naga Epic Chroma wireless gaming mouse, which is geared toward MMO players. In terms of hardware, its specs are pretty impressive: In addition to the 19 programmable buttons, the mouse has a 8,200DPI 4G laser sensor and 1,000Hz ultrapolling.
