The Tyon is the latest gaming mouse from German company ROCCAT and it features a large number of configurations and customization options. With 16 assignable buttons, the Tyon offers up to 31 different functions configurable with the Easy-Shift[+] Button. The Tyon comes with 576KB of onboard memory to save your settings, an 8200 DPI laser sensor, and programmable lighting choices. ROCCAT has also included two new technologies, the X-Celerator and Dorsal Fin. The X-Celerator is a "two-way analog stick that allows gamers to throttle, sprint, rotate tank turrets, and more directly from their mice," while the Dorsal Fin is a "two-click button placed behind the mouse wheel that provides comfortable mid-finger gaming action and increases mouse functionality."
