Summary: I have used this trackball for more than six years with my desktop. It took a little getting used to compared to a mouse that you move around, but I liked it right away. No worries about sliding off a mouse pad or bumping into things while using a mouse. Your arm is relaxed and resting while your fingers do the work. Its accurate and fast or slow as you set it to be. I just bought a laptop and I hated the finger pad. I bought another trackball to use instead.
Pros: Accurate Tracking, Comfortable Design, Fast Response, Glides Smoothly, Great Features, Works On Any Surface
Summary: I've used this Trackball for years and they are much better then a typical mouse. Lost the one we used for years in a recent move, out of desparation I bought a regular mouse YECH! We find it easy to use (might take a bit of getting use to but it seemed easy to us).
Summary: Allows fine control of the cursor without rolling around the desk/mouse pad. By keeping the mouse stationary you don't have to pick it up or reset it. It does not pick up lint and you can hold it in your hand and use it without loss of cursor control. It is also much better on batteries than my other desktop opyical mouse (laser on the bottom, standard slide around mouse) by a factor of 2 to 1 on battery life.
Summary: Good trackball that makes sense to use. Kensington has not caught up to this century when it comes to ease of use and ergonomics. Microsoft has stopped production of their superior product. So this is the best of the breed now. A large ball that you control with your fingers. Easy to reach buttons for left and right click. Forward and Back buttons, and a scroll wheel which is also a button conveniently placed.
Pros: easy to install, performs well, design, compatibility, build quality, features, easy to use
Summary: I have always been against wireless keyboards and mice. This Logitech mouse changed my view. It works better than my Logitech lasor mouse which it replaced. The only negative thing I found was that a couple of the buttons are a little awkward. Good for bigger hands. The mouse works flawlessly.
Pros: Accurate Tracking, Comfortable Design, Fast Response, Glides Smoothly, Good Battery Life, Works On Any Surface
