I'm using the Magic Mouse that came with my iMac. I like many of the features of it but I had to find a very large mouse Pad, 9 x 14 inch, because moving the cursor from one side to the other of the 27 inch display requires a wide "movement". I only see one setting in the System Prefs / Mouse, under the Point & Click tab, for "Tracking". I have it set to the 3rd fastest. I tried different speeds. It seems ridiculous to have a mouse pad that large and fortunately I have the desk space for it. Am I doing something incorrectly? Is there another / better mouse or 3rd party software to control the Magic Mouse?
