    I love the ergonomics of this mouse. Too bad that Kensington is falsely marketing it as a "5 programmable button" mouse. The software included with the product explictly states that it does not support Vista. How can this be? Vista shipped almost three years ago. It's really hard to believe that Kensington still does not support the most commonly used operating system. I guess they don't really care about their customers. Their software does claim to work on XP and Mac OSX, but if you're on Vista be warned.

    I've been using this mouse for about 2 years now for 3D and design work. I LOVE this mouse! The rubber grips are great. I like that I can easily maneuver this mouse with just 2 fingers. It's very light. I don't like heavy mouses where my fingers have to do a workout just to move a mouse an inch. I really like that it's so big. I can rest my hand on it comfortably. I don't use the mouse software so I don't really care what extra features it would offer. I just simply plug it in and go. Since I'm using it for so long, I'm thinking about getting another one, just in case they will discontinue making it (or it will break down), so I'll have a backup. It tracks really well for precise design work.

    My favorite mouse, an older blue and grey version of the Kensington 72121 Mouse-in-a-Box Optical Elite USB Mouse (PC/Mac), finally died after several years of use, and I took the opportunity to find something that might be even better. Understand that I'm a mouse snob -- for as much time as I spend using a computer, I want my mouse to fit like a glove. The Ci20 comes close, but has a couple of dealbreakers for me. The Ci20 is a big mouse, make no mistake. I like that. But the "hump" of the mouse lies pretty far back on the body of the mouse, so my hand tends to settle farther back on this mouse than on a mouse with its hump in the middle. This, in turn, pulls my fingers and thumb farther back. After a couple of minutes of use, the front thumb button goes out of reach. I like to hold the sides of my mouse with my thumb and pinky, touching my mouse pad as well. I momentarily use the base of my thumb and pinky if I want to click side buttons. The concave sides of the mouse start their curve very close to the bottom of the mouse, so my fingers naturally slid upward on the slick rubber, and I soon lost the tactile feedback I usually got from having my fingers touch the mousepad. I hate installing mouse software, so I plugged the mouse into my XP-based computer, and XP had me up and running in about 10 seconds. Kensington mice seem good like that, in my experience. The buttons click effortlessly, and the wheel has the best balance of smoothness and tactile feedback I've used on a mouse. The mouse isn't heavy at all, surprising for how big it is, and it glides effortlessly over my cloth-top mousepad. For casual use, this is great, but for a fun World of Warcraft battlegrounds run, the shape of the mouse makes me lose my precision. If Kensington relocated the front thumb button to the right side of the mouse (this mouse has the perfect shape for a right-side button) and didn't make the sides concave, I'd have a five-star mouse for the next half-decade. Essentially, This mouse impresses me with its quality and attention to detail, but it requires a fundamentally different mousing style than what I use.
