Excerpt: I like trackballs and I read that this was one of the best... but the feel of the scroll ring ruins the entire experience. I like the idea of the scroll ring and properly implemented it would make this a slam dunk.
Excerpt: I have used track balls for as long as they've been available. I bought this unit when it was on sale because it received 4 star reviews, and I'm starting a major graphics project and thought a new device might bring a new perspective to the work.
Pros: Accurate Controls, Easy To Clean, Smooth Movement, Well Made
Cons: Poor Control Placement, Tough To Get Used To, Uncomfortable, Wrong Wrist Angle
Excerpt: I bought my first Expert mouse 6 years ago and couldn't work without it since. I do lots of audio and video editing. The ball however got a chip in it and it became madening to use. Kensington does not offer a replacement ball (they want to sell a new unit of course). So, I bought a new one.
Not recommended for Windows; Mac Yes; Description is Grossly Wrong

Summary: The Description is Practically Seriously Plain Wrong. This is my favorite mouse (wireless version of it). I have bought about 6 of this type mouse/trackball, some wired, some wireless. I bought a 64213. I give it 1 star for a practically false description.
Summary: no drivers included, you have to download it and run the program in background. the ergonomics are bad for me, i have to use my index finger to roll the mouse. very imprecise for what i do.
Pros: reduces carpal tunnel issues, because it's stationary
Cons: trackball is not secure, can fall out and roll anywhere. scrolling has a gritty feel to it, not what you expect from a high priced mouse. the worst problem for me is the top 2 buttons have to be programmed, but they will stop working. also, you cant use a top button with a bottom button. you have...
Summary: My Logitech Marble is still working after 15 years of very hard usage through college, university, software analyst, and telecom jobs across 2 countries. Spare yourself the grief and go Logitech Marble Trackball (just bought another one of those today as a backup).
Pros: I bought the thing because of reviews of people who obviously have never tried other balls. It has 4 buttons. Wheel.
Cons: I found out the buttons weren't programmable out of the box, you had to download this horrible clunky program from their site. They have since tuned the program but it was just something that should have been made available long ago. It broke after only 2 years of moderate usage the eye just stop...
Summary: I purchased this because of all of the bells and whistles, and because it appeared to be comfortable. I loved the ball over moving a mouse around a pad, but none of the buttons could be programmed as the software for this mouse is not compatible with Windows 7.
Summary: Strongly recommend not getting this trackball if you are using Windows 8 64-bit and cannot live with the generic Windows driver.
Pros: Trackball itself is good. The scroll ring feels cheap, but otherwise the device is good. I like the large ball size and the buttons have a quality click feel.
Cons: The drivers for Windows made my system unusable. I had to unplug the trackball, plug in another mouse in order to regain control and get to the place where I could uninstall the driver. I ended up using the generic Windows 8 mouse driver. This limits the functionality of the trackball, and the po...
Summary: I want to set the record straight on a couple of issues surfaced on this board. I actually love this device. I gave it one egg so that people looking for disgruntled users would read this. I've been using Kensington trackballs exclusively for over 15 years.
Excerpt: I bought this mouse because Microsoft discontinued the trackball explorer with program specific buttons. This thing is BAD, I use it for autocad, sketchup, photoshop, etc. where you need program specific shortcuts. 1- this stupid mouse won't let you program "enter" as a button!?!?
Pros: Good weapon
Cons: Inaccurate, Slow Response, Tough To Get Used To, Uncomfortable
