Customer Rating:      Summary: Innovative design, short life Comment: This mouse has a fine design but is not a good deal for the money. I love the wirelessness, it is recognized by the Mac semi-reliably, and it tracks well. Clicking is awkward, it devours batteries (I use NiMH's), and worst of all ... the scrollwheel inevitably breaks. Once you get used to having the wheel you won't want to lose it, but you will.
My Mighty Mouse will not scroll down and I can no longer revive it. I have never been able to right/left click reliably (some say the trick is to first lift your finger, which is not easy. Finger position is sensed capacitively, not by pressure, as mentioned below.) I did not even want to get this mouse a year ago given all the bad press -- check out the Apple Store site! -- but it came bundled. They took the dirt-collecting defects of the old rollerball mice and put them on top of a laser mouse.
TIPS:
There are several approaches to fixing it; none works for me any more. You can clean from outside using water or alcohol; one poster suggested Purell. You can move the ball around vigorously to know teh dirt loose -- that worked for me for about a year. And you can disassemble the mouse usingh takeapart guides on the web or youtube, it's not that difficult, and carefully take the ball assembly apart. There are four magnetic rollers arounf the ball and they WILL be dirty. I have cleaned and swapped them around without no luck. I reseated the ribbon cable, too. (While you're there you can check whether the foil is properly stuck to the upper shell. It is the sensor for hand position and often malfunctions in distinguishing right/left clicks, including for me.) I think the Hall effect pickup or something on my circuit board is defective.
Whatever the solution, the Mighty Mouse is a neat design with poor engineering. When it works, it's great, and I love using bluetooth. Now I don't really feel cheated only because my expectations were so low to begin with. Good luck!!
Customer Rating:      Summary: Maybe a mouse really should have a button.. Comment: This mouse is functional. It is always registered with my Mac, responsive and smooth. However, its tactile feedback is very poor. Even after 1 year of use, I still find myself miss-clicking the left and right sides. The scroll ball in the center is small and hard and uncomfortable after some time. The "pinch" buttons on the side are mushy and offer no tactile feedback when squeezed enough to activate (I just gave up trying to use them). Finally, the mouse is very low profile and, as an average male, I find after long use my hand would really appreciate a physically larger mouse.
I strongly suggest against this mouse - it's pretty - but function fails to follow form.
Customer Rating:      Summary: Form and Function are Symbiotic Comment: I really like my mighty mouse. By far the best syncing bluetooth device I used with my Mac. The side squeeze buttons are really nice to have if you want to quickly access your dock or open your address book. I have had mine for about a year now, and my only complaint is sometimes the trackball acts like it has something caught in it, and will not want to scroll down. Shake it a little bit and it seems to work. Also, batteries last around 6-7 months.
Customer Rating:      Summary: Downward scrolling stops working Comment: I have had two of these mice and used them for over a year in total, so this review isn't based on a quick fist impression.
I have an iMac, two MacBook Pros, and iPods for everyone in my family, so I'm not an Apple hater. Therefore it pains me to call this mouse terrible. I really wanted to like it.
First, the performance of the Mighty Mouse is extremely average for the price, and the trackball is one of the worst ideas ever. Seriously, if mice evolved beyond using a physical ball for motion detection, why would anyone think a ball would make a good replacement for a scroll wheel?
To prove this point, after a few months both mice stopped strolling down. This is the most common use for the scroll ball, so it makes sense it would fail first.
Of course the mouse is glued shut, so there is no way to clean it. Apple's instructions (blow air) and a host of online suggestions failed to restore downward scrolling.
When my first mouse failed in this way, I disassembled the mouse (which required breaking glued seals with a sharp knife) and learned the cause of problem. The scroll ball sits on four cylindrical rollers, one on each side. The roller that measures downward motion had basically disintegrated. It wasn't that dirt had gotten in; the actual mechanism fell apart and clogged itself with broken pieces of roller.
The same thing is happening to the replacement mouse I purchased once I realized there was no fixing my last one, and I'm not going to give Apple a third chance. It's back to Logitech for me.
And finally, I also find the "squeeze" action needed to trigger the side buttons unnatural and basically useless.
Customer Rating:      Summary: Heavy. Comment: I had this mouse for a while a few years ago. Perhaps it has been redesigned since then, but at the time, I felt that the weight of the mouse was heavy, due to the batteries you have to stuff in there. It required extra effort to push it around my mouse pad. I didn't notice it as first, but after a few days, my hand felt fatigued. Also, sometimes it got knocked off the desktop and when it fell, it fell hard because of the weight. After a while it didn't work anymore and I was more than happy to go out and get a mouse that wasn't filled with batteries. Now I have the (overpriced) Mighty Mouse that has a cord, and it works fine, but the cord is about a foot too short for the giant G5 tower that I have. At those prices, why can't they get it right?
