If you are tired of touch pads or needing space to move your mouse around
you may want to attach to your mouse

The Mouse Tobbogan

This handy adaptation is a thin plate that fits to the bottom of your mouse.
It gives an overhanging support for your mouse so the only movement necessary, for the movement of your pointer,
is that of your finger as you place your hand in a natural position, palm up, below the mouse.

You move the ball with your finger and press buttons with your thumb.

Two styles; a desk top Mouse Toboggan elevator, which works with laptop and
the go anywhere Mouse Toboggan plate, pictured below.
