Summary: The Good: After ordering this item along with a motherboard from this site i was so surprised to see it sitting on my doorstep the next morning, also exited because they were the last pieces of my most recent build. The packaging for the mouse was decent if not better than most. After some digging the drivers for it were easy to find, easier to install, and has a background program that can hide in the task bar to adjust the 4 programmable along with the sensitivity of...
Summary: I purchased three similar products from Amazon simultaneously and received them today: Kensington Expert Mouse Optical USB Trackball for PC or Mac 64325 Logitech Trackman Marble Mouse Kensington K72337US Orbit Trackball with Scroll Ring for PC or Mac This is for a Mac. My large hands and my wife's small hands explored using all three devices. Our feedback on these products is in relationship to the other ones. -The Kensington "Expert" Mouse was too big and clumsy.
Excerpt: Trackball works great I'm pretty happy with my purchase but there are some downfalls. 1. The slide ring is not very smooth 2. I have to open the Trackball preferences for my custom settings to go into effect when I unplug my Trackball or turn my computer off. Pretty annoying. 3. I wish there were a horizontal scroll option. Overall work good but wish I knew these things before purchasing.
Pros: Accurate Tracking, Comfortable Design, Fast Response, Glides Smoothly, Great Features, Works On Any Surface
Excerpt: It's only been a week or so using the Expert Pro, and I don't think that's enough time to see if my RSI symptoms return. However, since switching from the Apple Magic Mouse and basic MS mouse I've found: Positives: -I like that I'm encouraged to keep my wrist steady with the Expert Pro, whereas on a regular mouse I tend to pivot from the wrist (read: bad) -I like the use of 4+2 programmable buttons, which keeps me bouncing less between keyboard and mouse and helps to...
Pros: Glides Smoothly, Great Features, Works On Any Surface
Summary: I use a Mac 10.6. The software seems to work fine, the only minor gripe is that when setting a button to 'scroll lock' (track scroll) using it with the trackball only allows scrolling in the vertical direction, replicating a scroll wheel. It would be nice if scroll lock allowed 360 degree scrolling with the trackball.
Pros: We have used these at our recording studio for ages - they are very versatile and use much less space than a mouse. I've been using a Logitech Trackman Cordless for ages but I finally got fed up with changing the batteries and the poor reception. Honestly, if Logitech made a non-cordless version, I would pick up another one of those in a heartbeat. That said, Kensington absolutely gets the trackball part of this right. It's got great weight, letting you 'throw' the cu...
Cons: Kensington has made a lot of compromising design choices in an effort to keep this a dual right and left handed device. The scroll ring is terrible. Kensington goes on and on about how great the 'precise fingertip scrolling' is in their marketing material. Using it mostly requires more than one finger, and is always accompanied by a grinding plastic-on-plastic sound. They really should be using teflon or steel ball bearings and give the scroll ring some weight rather ...
Summary: To begin, this is the fourth trackball I have owned. The first two were the old putty colored ones I used with my older Mac's and were much better quality. The last two were both the newer model K64325 - dark grey. For those contemplating a purchase, the ''stiff'' ball loosens up very nicely after an hour or so of use and is silky smooth. The scroll wheel is a different story. It is cheesy to say the least.
Summary: Went to the web site to get software since that is the only way it comes. Was going to look for support after the crash installing it caused and got several 404 errors from links inside their site as well as a "we're working on the problem" page. Despite having used a thumb oriented ball for a long time I changed styles because of what seemed like superior feel & function. Software and configuration was a disappointing.
Pros: Design and feel are superior. I have used a trackball instead of a mouse for > 10 years and had to pick a different model as the MS product I had was not longer manufactured. It is heavy and stays in one place. I use an IMAK wrist pad instead of the one that comes with it and it is comfortable to use.
Cons: Actually I own two of these. The first one I purchased for a Linux build and I didn't expect to get the all the buttons configured without some work. What I didn't expect is that downloading: 35Kensington_TrackballWorks_v1_0_4.exe and installing it would cause my Win7 Pro 64bit machine to lock up. Had to uninstall the software. At this point I'm not confident that the other buttons will be configurable for me.
Excerpt: Just bought this mouse for audio editing. I upgraded from the smaller two button mouse. I have used it for a few days and I'm still trying to decide if I like it. I really love the extra buttons and scroll wheel. I'm unsure about the ergonomics. I have discomfort with any mouse, but I was hoping that the wrist pad would help. It has helped with some discomfort, but possibly cause others.
Pros: Accurate Controls, Easy To Clean, Fast Response, Smooth Movement
