Quote: Today for review Im back with the final of three wireless keyboards fro m our friends at Koribo. This one is called the Vivar and it features a trackball as the mouse along with thirteen multi-media keys, scroll wheel and two sets of mouse buttons to round it all off. It has a nice soft rubberized surface to make sure you keep your grip, and all the while it provides you with the comforts of a full-sized keyboard.
