Summary: The ball stops working after a few months, and, as others have said, you can't then open it to clean it. Was going to take it back but it seems it happens to all of them so it barely seems worth it.
Summary: Was really nice to use until the little scroll ball stopped working. Wouldn't be so bad if you could take it apart and clean it but Apple in their infinite wisdom decided to glue the whole thing together rather than use screws or clips!
Summary: Yeah yeah yeah, there's the fancy window changing buttons on the side and of course the handy side scrolling... But it's so sensitive and has a mind of it's own! If like me, you've bought an iMac for editing audio on logic and video on FCP, this mouse will drive you NUTS!

Summary: I've been using Mac gear since the 80s and this is the first piece of Apple gear that I've come across that is fundamentally flawed. I've had three of these things and every one of them failed after a little while, always with the scroll ball ceasing to operate, sometimes intermittently and then...
Summary: Why attempt to 're-design the wheel'?! After approx 3 days, the ball will no longer scroll up-down. Initially, disconnecting, then turning the mouse upside-down & rolling the ball on a piece of material etc, is effective. Initially...
Summary: The Apple mighty mouse is overpriced and is poorly designed. The scrolling ball will only work for 2-3 months before it starts to stick. The grease on your skin will foul the rollers inside - and unlike other types of "mice" you cannot clean it!! So end up throwing it away.
Summary: I'm amazed there are so many positive reviews, it drives me completely nutty. The pointer is forever disappearing and I have to keep lifting it up and moving it around to find where it has gone off to. When I bought my imac the ones in the store did this and I hoped it was just the display models.
Summary: I have to admit that is just an amazing idea for mouse BUT IT DOESN'T WORK I have the wireless for more than one year and i have problem from the secong month with the dragball. however i found out that all my friends have the same problem.
