"The Mouse Bungee is quite heavy, and by any means will not slide off your desktop. The weight comes from a ball bearing thats about an inch thick and is placed in the center. Underneath the plastic assembly are rubber grips to prevent further slipping. Two springs are located along the center of the Mouse Bungee where the cord of your mouse is placed. The springs allow a very comfortable freedom of movement that does exactly what its designed for. It eliminates the mouse drags and cord tangles, and at the same time maintains a good tension that allows you to have a perfectly controlled mouse."
