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.

Best right-handed trackball ever
This is the best pointing device I've ever used, hands-down. This is the second one I've purchased since I've managed to run out the last one in 4-5 years of very heavy usage. Here's what I like about it.
The real centerpiece of this trackball is the off-center ball. Now, this does make this definitely a right-handed trackball and lefties will probably feel left out, but putting the ball off-center matches the general distribution of your fingers over your hand. It's been to be maneuvered with your index through ring finger, and it is perfectly positioned to roll to any of those fingers as you need to use the scroll wheel or the right mouse button. Compared to a more omni-handed Kensington and the comfort difference is astounding. Likewise, for me, this is infinitely more comfortable than using my thumb for the trackball. The trackball pointing devices that use the thumb inevitably make my hand and thumb joint feel jammed up.
Also compared to Kensington, having a proper vertical scroll wheel is infinitely better than their "orbit ring" in my mind. The index finger quite naturally lines up with the wheel. The overall shape fits my hand comfortably and makes for easy long hours working or gaming.
Construction is solid and it's durable with good maintenance. As noted I used the previous one for at least 4 years, and used it quite heavily for general computer tasking, through EDA tools (Modelsim), through heavy gaming (including FPS and MMORPGs). If you are a button hog, then you might run out, but there's more than enough for me to use and i'm quite pleased with what I've been able to make it do.
Defictis: There are few. As noted, if you are a left handed computer pointer... you'll have to go with a mouse or a Kensington. If you've trained your right hand to point this may work for you. The wireless aspect of the device is not it's strongest feature and there have been a few rare moments when it seems to lose its connection with the base station. And wireless range is probably a little limited, though I've used it successfully several feet away from the base. It does have a few dropouts in motion further away though, so don't use this for a large presentation room or TV gaming.
But that's pretty much it. The sad thing is that Logitech doesn't seem to push this product into stores, so it's a bit hard to find on the shelf where you can do a touch fit. They've used this form factor for awhile though, so hopefully it'll continue to be useful in Amazon sales and make a comeback in a new product again soon. I"m tempted to buy another though to have in reserve in 4-5 years though!

Great Ergonomics
Color: Black
I had bought this keyboard back in 2012 when I had tendonitis and needed to make my entire work set-up more ergonomic. This keyboard helped immensely! This keyboard comes with the extra bottom attachment to lift the keyboard, but I always found it more comfortable to use the keyboard without it (maybe just add a wrist-rest if needed). I type pretty often and very quickly, and it was easy to adjust to the split layout (only took a couple hours to remember which keys to hit with which hand...). The quality of this keyboard is pretty decent - I would still be using this keyboard to this day, but it had one-too-many liquid spills back in 2020 to the point that certain keys would not function, so that was that.
I have used this keyboard for windows, linux, and mac (primarily mac) and can say that all the regular keyboard functions worked. All of the extras (i.e. 'media' buttons along the top and center) were inconsistent about working and depends on what system you are using. I didn't take too much time to force it into working, since I didn't really need those functions. I also travelled for work with this keyboard - although it's bulky, it does fit in the check-in bags, and the wired function is convenient since it doesn't require batteries.
Although I loved this keyboard dearly, when it met it's untimely death, I looked for a replacement and I was surprised at the price this keyboard is currently at. It's definitely not something I would be able to afford back when I was working barely above minimum wage... I can't promise if it'll be worth the cost as there are other alternatives that could work just as well at a lower price. However, my experience of this keyboard was definitely excellent and met my ergonomic needs.

Works for what I need it for
Color: Black
I've been using this type of keyboard for years. I remember back in the late 1990/early 2000s, I was working as a medical transcriptionist and my supervisor at the time was using a "curved" white Microsoft Natural Elite keyboard. I was still using the typical, out-of-the-box, straight keyboard. She gave me hers to try out for a while. At first, I HATED it. My typing speed was terrible, I was pressing every wrong key, etc. But after I got used to it, I realized there was no way I could ever go back to a straight keyboard. Now, all of these years later I'm still working as a medical transcriptionist and have graduated up to the Microsoft 4000. I still have problems using a straight keyboard - in fact, when I'm using my laptop for work I cannot use the laptop keyboard and have to hook up my own keyboard in order to transcribe.
Compared to all of the other "ergo" keyboards out there that I have tried (and I have tried quite a few), this is the best I've found. Now, I have never tried the Kinesis which I hear once you try and actually get used to you will never go back to anything else ever again and that it's the "best of the best." I have thought about trying one of those out, but I just cannot justify the cost. Perhaps if I was suffering from more carpal tunnel symptoms, more wrist pain, etc., I would give it a try, but as of now the Microsoft 4000 works for what I need it for. I am pairing it with an Anker wireless mouse, which took me a while to get used to but now I couldn't function without it! My sister was visiting me a few months ago and she was having a terrible time using my keyboard and mouse just to function on the internet and I then realized how somebody who isn't used to it feels. As I mentioned above, I've been using one of these "curved" split keyboards for nearly 20 years now, so I'm definitely used to it. With this keyboard, my hands feel like they are at a more natural position compared to a regular standard keyboard where they feel to be unnaturally squished close together.
When I worked in-house at a local clinic (I currently work from home), we had occupational therapists come over to evaluate our work stations, etc. I was told I have hyperreflexia and that the best position for this keyboard was to keep the lower bottom "riser" attached and to keep the top legs folded up so that my hands are sloping down from my wrist placement. That is the best position for me, but others may be different.
As I mentioned before, I have used this brand of keyboard for years, though I need replacements every six months or so as I am definitely NOT easy on my keyboards!! I always keep a spare one around which is good as the other day my Diet Coke spilled all over the one I was using. I thought I caught it early enough and got it all drained out, but nope, it was (and still remains) dead. So the spare I keep around does come in handy!!
All in all, this is a great keyboard for those of us who type on a regular basis. My only complaint (and this is not with EVERY Microsoft 4000 I've purchased, only a few) is that there are times when the space bar is a bit sticky. I pound the keys so hard while I'm typing that I generally don't notice this, but I have had a few that I have noticed it on. Otherwise, all keys seem to depress well. The letters on the "common" keys do wear off around four or five months, but that is something I could care less about as I don't ever look at my keyboard when I'm transcribing (though those that attempt to use my keyboard have commented on it)!!
