Kensington Orbit Trackball Mouse (K64327F), Silver/Black

Having used the Logitech trackball for years, but when it was time to replace Logitech's prices went too high. So, recently tried the Kensington with the Ring and found it to be too wide for most hands here...to the point of being uncomfortable and clumsy. Decided to take a chance on this one without the "ring" and what a difference! The width is just right and the ball moves ever so smoothly and quickly and stops easy too! It is being used on a Linux O/S and absolutely no problems. Highly recommend this mouse.For those who need to know the size width:The narrowest part where your hand lies across the top (to click either left or right side of mouse) is approx. 2.25 inches. Compared to the same brand with "the ring" which is approx. 3 full inches. Also the highest height of the ball on the "ring" model is 2.50 inches and on THIS model it is a half inch lower. SO you can see by these measurements this model is much more suitable for smaller hands, or hurting/stiff hands.Additionally, other reviewers stated that the trackball is loose and falls out...I too noticed that my trackball was not seated all the way in. I took it out and examined it and saw that there is a clear piece of plastic that was stuck on the ball and had rolled to the under side of the ball. It was hard to see because it was clear and had black writing on it and the ball is a very dark gray. I think this piece of plastic had some warning on it -- maybe to remove before use...but it was difficult to see. Now that that is removed the only way I can remove the ball from its place is to turn the mouse over and it gently falls out so that you clean/dust it off. It never just falls out or pops out...unless something is in the way.Its a great little mouse...thinking about getting another one!

I had bought and used a trackball in the past for a pc and a Mac. The old Win 98 pc bit the dust long ago and I graduated to a newer desktop. It came with a mouse of course and I used it for several years up until recently. It was when my boss at work talked about her wrist bothering her so much that it got me to thinking. Maybe it was time to look into getting another trackball again. I've been using this particular model for a couple of months now and it brought back the good memories of how good it feels to be able to fling the cursor quickly from one place to another on the screen. The only thing that I occasionally miss is not having the 'scroll wheel'. You have to move the cursor all the way to the right side of the screen and click and hold onto the slider to move the page up and down. With the scroll wheel you can just roll it up and down without clicking anything. It's not a big deal to me though as I can move the trackball marble about 160 degrees to get from the far left side of the screen to the other and then click and roll. I picked Kensington as that is the brand of trackballs I had bought before and their products are built well and look good also. One commenter mentioned that there is a slight dead spot when rolling the marble. I found this to be true. He had gave the technical reason why this happens. I believe it was from the way the ball is designed but again, it's not a big deal and you can easily get used to it. I now anticipate it happening and when it does I only have to move the marble a bit more to get where I want to go. My end statement here is that this model was a good budget price. I did not want to spend the $79 again for the deluxe model I had bought for the Mac many years ago as I felt it was overkill at this time. The deluxe or better priced model had a very fine movement to it with no dead spots that I recall and was very well suited for the desk top publishing I was doing at the time. Keep in mind another reason for getting a trackball is not having to pick up a mouse every once in awhile to get more cord. Try one, you'll wonder why you never did before.

It's harder to find the old-style trackballs where the ball is in the middle and not on the side. This is pretty close and is very comfortable. I use it every single day, 8+ hours a day and have had zero issues after almost a year. Great mice, great price.My only nitpick is no scroll wheel, but you get used to pressing Pg. Up/Pg. Down and arrow keys. Something I was doing with my older trackballs anyways.
