Ring Mouse is a lightweight wireless finger-held device. Breaking away from the mouse, it is highly flexible and free to use at any spaces. With its minute touch sensor, cursor control can be easier and more precise. The discreet design features an ergonomic rubber holder, which is a good match not only for both hands but also for keyboard typing. Either index or middle finger is ideal for wearing. Built-in Genius software transforms Ring Mouse to a controller, which is more intuitive for users in terms of web surfing, music listening, video watching, photo viewing, presentation and e-book. With a lithium battery, one full charge allows one month of use.
