Simply the best input device I've ever used
I've been a long time fan of trackballs - most especially and specifically those made by Logitech. About five years ago I started having pain in my wrists from the constant side-to-side motion of using a mouse. I picked up a Logitech Marble Mouse and loved it for years. It instantly helped by wrist issues and I didn't get so strained and hardly ever got soreness.
The only thing I didn't like was that there weren't enough buttons. I envied things like a scroll wheel found on regular mice. The thumb trackball was horrid in my thought (all that stress where your thumb meets the wrist; Ouch!) but had the extra buttons I longed for.
Then this one came along. Wow. I saw it in the store and I'll admit, I was a bit intimidated at first. Did I need a cordless? Could I get used to moving it with my hand in a slightly different position? And I know I wanted buttons, but woah, there's a LOT of buttons on it!
I played with it and daydreamed about it. I finally ended up getting it for my birthday in May 2003. It honestly did take me a few days to adjust to the change (even from one Logitech trackball to another), but now I can't imagine ever going back. The sheer convenience of being able to not only left-click/right-click, but scroll AND easily go Forward and Backward through webpages with a click of a button amazes me everytime. Trackballs already cut down the amount of round-about pointing you need to do by making it much smoother and easier because of less motion required, but this cuts it down way more then that.
Some thoughts from other reviews:
*Lefties -- I'm sorry, but it really is designed for a right-hander. Like most mice/trackballs on the market today, they aim for the majority. It's usable on short term for lefties (my boyfriend's a southpaw and he can maneuver it, but couldn't really use it every day, day-in/day-out). HOWEVER, a nice option is the Logitech Marble Mouse since it is neither left nor right hand specific.
* Cordless issues -- I've had ZERO interference with it and I have a USB Wacom tablet as well as digital camera hookups and other usb items in my usb hub. NEVER a problem. The manual recommends that if you have problems, move the receiver away from the monitor. Mine sits two or so feet away and works perfectly.
* Battery life -- WONDERFUL. Mine went for about five months or so on the original batteries it came with. And I am a hard-core user, driving my trackball way over ten hours a day. The program even warns you on-screen that your batteries are getting low. How cool is that? You don't have to wait until things die leaving you without a mouse, wondering what went wrong - it tells you!
* Weight of ball -- I have to say that one of the best aspects of the Logitech trackballs is that the ball spins VERY smoothly and easily. It's also not heavy. This sounds weird until you try one of the HORRID Kensington ones which has such a heavy ball that you literally get fatigued fingers from trying to push the darned thing around the screen. It's such a battle with inferior ones whereas, with the Logitech ones, it's easy. I can zoom around the screen as fast as I wish with the slightest touch of my fingertips (*note: the speed and such can also be edited if you like a slower cursor, but it still will have the lightweight Logitech is known for)
* Range of Use -- I agree with another user here - this thing has a range that's far more then you'd need. I sometimes use it on my lap and can stand up and control it from several feet away.
* Cleaning -- IMPORATANT. Every now and then, pop the ball out (by pushing from underneath) and clean the gunk which gets on the points the ball rests on. It will help keep your ball rolling smoothly.
In sum: ergonomic, comfortable, works great and a real Logitech winner. Well worth the cost.

Great, yet, not so great
I never bother leaving reviews, but this one gave me an opinion that was strong enough that I had to say something.
Much like many other reviews out there, a lot of people complain about the placement of the buttons. Actually I think for the most part everything is fine except for the scroll wheel and the default left click. My problem with those two is, if you're using your index finger to use either feature, you have to really stretch your finger outwards to access it. If you tilt the whole device so that it reaches more easily, then the thumb buttons are now at an odd position. I do have to say though, I originally thought that a non vertical hand position would kill my wrist but surprisingly it didn't. It didn't save my wrist either. But creating finger pains isn't exactly a good alternative due to the uncomfortable positioning. Yes I know you can remap the buttons to different functions but that's settling for less as that means you're opting out on using the uncomfortable buttons.
A quick little history on my previous devices. I've used regular mice like everyone else before all these problems creeped up on my hands. The most comfortable regular mouse for me is the logitech mx revolution. But eventually using that started to cause pain. I then moved onto the evoluent vertical mouse 3. That mouse is great and I still use it depending on what I need it for. However I recently ordered the zero tension mouse and I find that for overall usage, that one is the most comfortable since your wrist is at its most relaxed state. No twisting of any kind. Not only that, the fingers curl naturally along the device to reach the buttons. Some people palm their mice leaving their fingers straight, but for others with longer fingers it's a bit difficult to use a mouse without curling your fingers backwards a bit to accommodate positioning.
What is the whole point of that long paragraph? This trackman doesn't allow your hand to be in a resting state and *may* cause more strain, or a different type of strain in addition to whatever problem you may already experience.
While it sounds like I'm claiming that this is the worst pointing device ever, I'm just stressing on the bad points. It's definitely a solid piece of technology. Doesn't feel cheap, the ball is super easy to clean along with the insides where some dust may collect. All the buttons feel solid. Overall it's got heft so that the whole thing doesn't slide around during use. But build quality and maintenance takes a backseat if comfort isn't there.

Macho Macho Mouse!
This is the biggest mouse ever! At least the biggest I have ever seen or held. It is more like a large rat than a mouse. It was a bit too large for my petite/medium sized hand (I should have read the dimensions more carefully). I did not like the long cord it came with, and the device at the end of it for wireless capability - not very portable. The lock button malfunctioned and just quit working. The scoll buttons are too close together for me and too small. The ball was nice and smooth, but it did not ease the pain in my hand as I had expected. But I have inflamation issues. If a smaller one were available, it might have worked better for me, but the design/layout of some buttons didn't work for me. I surmise that this mouse works superb for men or women with large hands. But it was just not a good fit for me or my work area, and it malfunctioned. I ended up buying and loving...
My husband, who is utterly finickly about his mice, actually found this one comfortable and easy to use. The biggest reasons for a trac ball mouse are 1) it works nicely by my side when laptopping on my bed-top - no need to move the mouse around, only the trac ball. 2) The ball and buttons do not cause inflammation in my hands.

Great for radiology
I work intensively with computers. In radiology, the number of data points to process quickly is multifarious: dictation software, PACS, and workstations, 4 screens, etc. Volume is also inherently high. I've used this product for two-years and am very satisfied.
At times, I was finding wrist fatigue a bit of an issue with the classic two-button mouse with a center roller. My symptoms were nothing serious, just irritation at the end of each day from "clicking". I purchased this roller as a trial, to see if I get any relief. It worked just as I had hoped. I have no symptoms during or at the end of the day. I not will not go back to just a mouse.
Build is very comfortable and solid.
Ease of use. For me, it is a 5*, but you should know that it does have quite of bit of complexity. As you can see, it has any number of buttons--which I was specifically looking for. I find that these myriad buttons are very functional and easy to use in practice. You just have to map out what are high volume or repetitive motions/keystroke actions. Now I love Macs and their simplicity (and this trackball also works nicely with them), but their mouse is too stripped down for my needs.
I am someone who uses keyboard shortcuts whenever possible to speed things up. And again, in my business, speed and accuracy are critical. I already was already maxed-out with mere two-button mouse. This trackball allows me to custom assign functions and keyboard assignments. For instance, page-up and down are assigned to arrow buttons on the trackball. Now when I'm on a website or scrolling through ultrasound exams, I just click rather than moving to the keyboard. To initiate a case dictation is typically alt-8: now this function is tasked to a button on the trackball. Clicking the middle mouse scroll wheel is now assigned to mini-scroll wheel on the trackball. And so on.
I worried that the trackball would have trouble interfacing with the programs I used. It essentially had no problem. It was recognized across the board. There has been only one function that still requires a mouse: a shortcut I use for zooming on the PACS is to hold down the option key and spin the center wheel. For some reason I am unable to replicate this function. Because the zooming shortcut is something I use all the time, the mouse stays on my desktop next to the trackball
Which brings up another nice feature of this product: it can co-exist with a mouse. I plug the wireless transmitter into the front USB port and leave the mouse connected in back. I can use either device whenever I like. If a colleague comes over to review a case, they never know what to do with the trackball so I just move it out of the way and they use the mouse. If I move to a different workstation, I just unplug the transmitter and move and plug it into the next computer. The trackball will need to be configured as a first-time each time you start on a new computer, but done the profile will remain. There is logitech software that needs to be installed, but all of the mice are logitech, so the software for adjusting the trackball is for me already in place.
My productivity is higher and I have less frustration thanks to this device. For not only does the device allowing me to short-circuit and subsume common tasks, but it it simply much faster than a mouse. You can adjust the speed of cursor tracking and you can also embellish cursor movement with an accelerator. With multiple large, high-resolution monitors, this is very rewarding. Everything is faster. When I have to review a case on a colleague's workstation with a mere mouse, I am given a glimpse of how I used to work: the mouse is sluggish and I have to do a lot of wrist movement. Sure, the conventional mouse can itself be accelerated, but you still have the basic fact that you have to keep moving your wrist to cover four screens and to scroll through hundreds of images. I appreciate afresh that I am using a trackball and not a mouse.
Lastly, I do have to give high credit to logitech itself. 6-12 months into purchase, the buttons I had assigned to serve as "page-up" and "page-down" were not responding 100% of the time. Sometimes that signals that the AA batteries are wearing out, but even with new batteries the issue persisted. I called logitech and they switched out the device without any questions. Really top-flight service. The replacement is going on strong after 1 year.
So in short, if you are considering a trackball, get one. This one is I think the top of the line. If you don't need to extreme functionality, consider the Logitech Trackman Marble Mouse which has fewer buttons but works on the same principle (I actually use the marble mouse at home, because my at-home use is much lighter).
I have read about "review mills" that churn out praise or scorn. I find Amazon's reviews to be a great source for separating wheat from chaff. It has a critical mass of users and reviewers. That said, when I was looking for a trackball, however, I did not see a review that was on-point for my niche needs. Hopefully this review will fill that lacuna.

Solid Hardware; Doesn't fit all hands
I use Windows 7 Premium 64bit and I also run Windows 7 Ultimate 64bit in VMware workstation for work. All buttons and functions work properly in both the host an the guest machines.
This trackball is solid Logitech. It feels substantial and the buttons and track back are well made. Cleaning the trackball is a snap. Just pop it out, give it a wipe, and done. The software is also very easy to use and to customize the buttons to your liking. I am not a huge fan of the external USB radio transmitter that is used and that alone might have stopped me from buying this). It does not use the Logitech USB receiver other mice use, so I wouldn't recommend trying to travel with it.
The programmable buttons are great. I like the default assignments, but I programmed the scroll lock button to send "Enter" instead. I have set-up Windows to move the mouse to the default button when a dialog appears, so I can just hit that key rather then moving the mouse or moving my hand back to the keyboard. It's a little thing, but it's productive.
A note about fit. I did not ding the score for fit since fit is very personal. What I like may not be what you like. But here is my $.02.
If you can get to a store to try it out, do so. I have average sized hands for someone who is 5' 9" tall. The Trackman is a little bit big to easily get to all the buttons. I tend to rest the side of my hand on the desk which means I can easily get my index and ring fingers on the ball, my ring finger on the right mouse key, and thumb on the left mouse button and the forward/back buttons above the left click. The other buttons along the top ridge are out of reach. I have to shift my hand. Not a huge deal until you consider my hand is now out of place with respect to the trackball and buttons so I have to shift back and forth. It's an annoyance for me.
I have tried moving my hand up to rest more on the ample real estate on the back of the body, but that is more uncomfortable. I also tried floating my hand over the unit. That hasn't stopped me from using the Trackman, but I am not likely to buy another one these models. However, if you find it fits your hand, then this I highly recommend this trackball.
