"Scrolling Ball Failures and How to Clean It"3.0 starson by pescado
Pros: It's pretty and it works well in the Mac OS.
Cons: Nowhere near ergonomic, side buttons require too much pressure to use, battery case lock flimsy and scratches surfaces, scroll ball must be cleaned monthly. Nearly useless when running Windows in Bootcamp or Parallels.
Summary: Although Apple pioneered the use of the computer mouse, the company has never made an attractive, comfortable, or highly functional one, and the Mighty Mouse keeps the underwhelming tradition alive. I've owned this mouse over a year; so unlike Apple Fanboys who gush over products five minutes after they've owned it, I'm qualified to complain. Ergonomics basically don't exist because the uncomfortable pod shape forces your wrist into a sharp angle. Pressing the side buttons requires lifting your wrist and pushing hard at the same time. The battery case lock is flimsy; and after one year of usage, I'm concerned that it will break one day soon. The case lock also scratches your desktop if you put anything more than extremely mild pressure on the mouse. Battery life sucks. Even long-life batteries last only about two months.
But the worst thing is the scroll ball. Ironically, this was my favorite part of the mouse when I first got it?for about six months, vertical and horizontal scrolling were effortless. Then one day, the ball didn't work anymore. I figured the sensors were dirty, but couldn't find anything on Apple's website about how to clean them. A quick Google search proved this is a problem with the Mighty Mouse engineering, and wiping the ball repeatedly with an alcohol swab fixes the problem. Well, it did, anyway. I have to clean the scroll ball monthly for it to function properly. Turns out the material used for the ball basically scrubs the dead skin cells off your fingertips and collects them inside the mouse. This is a major product design failure on Apple's part.
Finally, the mouse barely functions inside Windows.
I've read the bad reviews regarding Apple's new touch-sensitive Magic Mouse, but regardless of its problems, the simple fact that it doesn't have a scroll ball anymore makes it better than the Mighty Mouse. If you're torn between the older and newer models, suck it up and deal with the Magic Mouse's faults. Of course, you could always get an after-market mouse, but then you wouldn't have the all-important fruit logo on top.
