The Genius Mouse Ring Presenter is an updated version to its predecessors the Mouse Ring 1 and the Mouse Ring 2, and is an excellent way to give presentations without fumbling around holding onto a giant mouse. The mouse is meant to be worn on the inside of your index finger and used with your thumb to move the mouse and click the buttons. The mouse ring features a natural rubber ring for comfort and grip, has an onboard screen to display actions, has a laser pointer to point into people's eyeballs, allows you to do all the functions of a regular mouse such as double click, dragging, and scrolling, is rechargeable using a micro USB connection, and measures1 inch x 1.3 inches x 1.4 inches.
