Roccat Kova[+]

Armed with the latest proven ROCCAT™ technological innovations, the successor to the ROCCAT™ Kova is equipped to the teeth. The new ROCCAT™ Kova[+] unites powerful technology with intelligent software and an advanced V-shaped design for left or right-handed use.
The Easy-Shift[+]™ button doesn't just give you access to seven mouse buttons plus the mouse wheel – you also get access to 16 additional functions at the touch of a button. The Easy-Shift[+]™ button is similar to the shift key on a keyboard. If you hold down the Easy-Shift[+]™ button while pressing one of the other standard mouse buttons, you can program a second function (dual-assignment).
