This a small optical mouse that unfortunately does not work in that the button functions are set and you can't change them. For example, whenever a dialog box opens with a default Yes or OK button, the mouse cursor automatically moves to that button. This is an option for an intellimouse, but the option can be turned off. The Targus website says that these options are not changeable. I personally cannot use a mouse that moves the cursor by itself - I've tried for two weeks and, while writing code, have had to do some rewrites.

Otherwise, if you don't mind this functionality, it's a nice mouse. I'm returning this one.
