people at apple store suggested i get a kensington, upwards of over $100, I figured this would be a great value. Unlike the other major brand, its quality matches the price.
there seems to be missing one of the small "ball bearing" sensors moving the ball, and it is difficult to clean as opposed to experience.
performance matches quality

After having 3 optical mice go back on me in the last 6 months or so, I am becoming more and more convinced that these optical pointing devices are not durable as much as the good old ball-mouse and trackpads used to be.
I still have a couple of serial (PS/2) mice and Mac Plus mice still working, and yet the optical stuff doesn't work. I was told, not too long ago, that if there is debris or dust particles underneath where the light shows that the optical mouse wouldn't work. Well, where are all those promises about "no more mouse ball cleaning" optical pointing devices are "maintenance free"?... blah blah, well I cleaned them and nothing. At least the old ones worked when you cleaned them!
Well, I decided to order this trackball about 2 months ago. Yes, about 2 months of use and its malfunctioning; specially the left mouse button. And that only includes durability, here are the other problems I had BEFORE it started to go bad:
1. The ball keeps coming out. This is not hard, since I use this with an iBook and sometimes sitting on my bed, if I move there goes the ball. Also, when it comes to having children around this device, my 3 year old son keeps running away with the ball. I used to own a trackball previously (5 years ago) which had a detachable cover around the ball, which would prevent it from coming out. It was easily removable so when you really wanted the ball out, you would just lift the cover by pressing on both sides and there it was. Meanwhile, the ball coming out on this device is more of a problem when carrying it. Since I use a laptop, this is a big issue for me.
2. Awkward positioned buttons are too sensitive to the touch. I find myself clicking on them by accident when setting up all the time. If I put a book, or any item near the trackball, the buttons get clicked. When connecting and disconnecting USB devices to my laptop, or when I pop a CD in, there it goes again. The problem is, these buttons are INDEED sideways. In the picture the curvature of the trackpad is not too evident, you learn about it when you actually use it.
3. It takes some time to get used to, more than a mouse or another trackpad would. In a couple of days I got used to most pointing devices I got previously. It took me one week and some days to get used to this. The look of the design might "seem to be" an easy design to work with, but I ask myself 'Did they bother to test this device in the company at all'?
Well, do respond to this review if you've had the same issues. I am quite disappointed, it is a shame better pointing devices can cost hundreds of dollars where is this world coming to?

I love these trackballs.
This is my third purchase of the Kensington trackball, this time for my computers at work.
Good price and they do what I need done.

I find it more useful than a regular mouse, and I love the fact that it is also Mac compatible.

I ordered the Kensington "roller ball" mouse because I had used it extensively at my job. I wanted the same comfort and convenience at home. I enjoy the product and it has saved my elbow, lower right arm, and even shoulder from pain due to having to move the standard mouse around and the darn scroll 'thingy' in the middle of it which caused me pain. I would recommend it for anyone having problems using a regular mouse. If you need to do a lot of "mousing" and extensive typing, you may wish to consider having a roller ball type mouse for each hand so you can switch off and give your dominant hand a rest. It does take some getting used to, but after you have mastered it, you will feel like you are being more productive and with less stress and pain. I like the fact that this type of roller ball mouse isn't too elevated and your hand isn't perched up too high where your wrist is bent up too high either.
The only problem you might have is if you have severe trouble moving your thumb and/or fingers because they do the "walking and working" for you instead of your arm and elbow. So, keep your old mouse if you have thumb surgery, but otherwise give this mouse a try!
