Just got this mouse from MacAlly. I'll tell you later if it works or not, I'm still charging the batteries. It's a really nice mouse, it fits my hand just right. Can't wait to try it.

I use the Macally mouse too. Mine is the opti junior. I like having a two button mouse. The right click is the control menu. I have my scroll set to one page at a time and the scroll click is the back button. Because... Safari does not have a right click back button available like IE does. So rather than having to navigate to the upper left hand corner of the safari screen or control click to go back I have programed the scroll button to do that. One press of the button and I am on the previous page.

Cool. I like optical mice better than trackball mice. Do you have a preference?

UPDATE: My batteries are fully charged, and my mouse works wonderfully. I have it configured just the way I like it. :)
