Query: Not for big hands

The shape and size is such that men with large hands will have a lot of trouble. The narrower front combined with the stiff buttons that are located too far forward cause the mouse the push backward. There is too little room for the thumb on the side to allow one to hold the mouse still with the thumb without pressing the side buttons too. It is difficult to pick the mouse up without the thumb pressing the side buttons. In fact, I had to type this review twice because an accidental press of the side buttons caused the first review to be lost. The mouse might be better suited to child-sized hands.
