ケンジントン Mouse Trackball Optical Orbit [並行輸入品]

Fits the hand well. Easy to set up. I have been using a well known marble mouse for years, but it appears to be obsolete now. Any on the secondary market are horrendously overpriced, so finding this as a replacement is great.

Orbital mouse great - Used one before hence using again.

Objet permet à des personnes qui sont atteints du tremblement essentiel de pouvoir cliquer sur un ordinateur sans utiliser une souris trop compliqué

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've always wanted a trackball mouse, after using my aunt's awesome Logitech one I've always wanted my own, late last year I finally got one. The Kensington Orbit is a comfortable and easy to use trackball mouse. Compared to some other trackball mice it's design is pretty simple featuring the Trackball and the right and left click buttons. Its a minimalist design that serves the product well. It's pretty light and not as chunky as some other mice. My only gripe with this is the fact that it dosent have a scroll wheel, so if I want to go down I have to track back to the scroll bar and manually scroll down. That being said there is more good than bad here. This is a great little mouse and I'm happy with my purchase.
