Practical mouse that is losing quality.......2008-01-01
I bought this product before, more than a year ago, so now I have two. However, the old one had a better build quality. The plastics now are cheaper and lighter than they used to be.
The Best Mouse Ever!.......2007-12-21
This isn't the first Logitech Trackman Wheel Optical that I have had. The first one I had for a long time, but it eventually went kaput like all mouse do. But it's so much better than a standard mouse, and better than the marble wheel type with the roller ball in the middle. This one has the roller ball in the thumb and is much more natural and easier to navigate than the other type. I will always recommend this type mouse over standard mice or any other kind!
The best.......2007-12-21
Logitech USB/PS-2 Trackman Wheel Scroll Optical Mouse (904353-0403)
I love this mouse. I had the wireless one first but after dropping it on a very hard tile floor about 10 times (clumsy of me), it didn't work anymore. SO, I went to Amazon and ordered three of the wired ones. I'm afraid one day they'll discontinue this model and I want to be sure to have backups if the one in use dies. The thumb wheel is the greatest feature. No moving the mouse or the hand. Just place your hand on the mouse and the click buttons and the thumb wheel are right there.
Good mouse.......2007-12-18
I've been using one of these for quite a while now. I purchased 2 more, one for my laptop and the other for the laptop at work. All have given great service. Excellent ergonomics and as long as it's clean the motion is crisp and smooth.
Can't Live Without It!.......2007-12-15
The very best trackball I have ever owned. This is my second one, the other I wore out. Can't imagin going back to a mouse again. I've tried other trackballs, but this is the one for me. Way to go Lgitech!

No more back problems!.......2008-01-01
I consider myself something of a power-user: In addition to the mouse, I also use keystroke commands for various applications. My father also uses a mouse left-handed, which made me consider using the trackball with my left hand -- and still use a mouse with the right.
In short, I have a great setup. I can now alternate how I interact with my computer, and reduce repetitive motion. The symmetrical trackball allows me to use my left hand, and the Logitech marble mouse places the thumb on the primary click key. The scrollwheel *is* missing, but, with two *raised* buttons near the primary and secondary (ie. right and left) click keys, you program one of the raised buttons. (I would initially recommend the up/down Autoscroll over the up/down/left/right Universal scroll configuration.) This leaves the secondary raised button for as a "function key" for whatever purpose you like. For example, if you regularly shop on Amazon, you may end up programming it as the Back button. Myself, I have it set as the Enter key, so I neither have to drag the mouse to the OK button (inconvenient), nor use my other hand to hit the Enter key (laziness!).
And, as said, my back problem is gone! With a USB hub, you can easily set up your desk to use both the track ball and a mouse. Use whichever you feel like to break up the repetitive motion!
Good ball movement but lack of scrollwheel got to me.......2007-12-31
The good:
It is nice and easy to move around using the big ball placed in the middle. More comfortable than using a conventional mouse.
The bad:
No scrollwheel. This can be overcome, as other reviewers said, by using shortcut keys. But I couldn't get used to those. Also, the two small buttons on the sides are inconveniently placed.
Conclusion: if you don't scroll a lot, this mouse may be a great buy for you. Otherwise, consider the other models with scrollwheels.
Good but not as good as the older one........2007-12-28
I love using trackballs and this is one of the few that I can use to switch hands with. I like it because of it's not very big, smaller than an average size hand. I had an older version of the Marble Mouse and after many good years, it was time to get a new one. This one has more buttons on it but the extra buttons are not exactly in a great position. It's kind of awkward to use them if you're trying to be quick. And one function that the old one had (pressing both buttons at the same time) is not available on this one. That's really irritating for me. I used that function to double click and now I have to do it the old fashioned way. I did set the double click on one of the extra buttons, but like I said, it's awkward to use. I can't believe they didn't add that function onto this one. Other than that, it works great.
Works Very Well With VMWARE.......2007-12-21
This rating is specific to use on VMWARE. I own an Apple MacBook Pro using VMWare Fusion. One of the problems with using a mouse that has software to control special functions is that it doesn't work very well when you move from one enviornment to another.
I expected as much with this device, the software for the Mac would not work in the Windows enviornment and I would have to install the Windows version on the Windows VM. To my surprise, this was not necessary. I only had to install on the Mac. The transition from one enviornment to another was not a problem, I could move the mouse pointer between the two enviornments with the same amount of control and no loss of synch or speed. The scroll buttons work perfectly in both enviornments, again with no loss of synch or speed.
Good choice.......2007-12-08
Logitech Optical Marble Mouse (USB/PS2)
I purchased three of these for clients, all of which have arm tremors: Parkinson's disease or old age. Two of the clients are left handed the other is right handed. The Logitech Marble mouse has turned out to be very near to perfect for these folks. While the price was not paramount, this is a low ticket item. It can be used with either hand, as the track ball has a central location. It is heavy enough to stay put with either a desk top or lap top.
There are disadvantages to this mouse. There is no scroll wheel, but scroll options are available. Something that I seldom do, the installation instructions need to be read to select the appropriate options. Finally, there is a frustration of learning a new mouse; however, that frustration is insignificant to the frustration of the inability to navigate a traditional mouse due to involuntary arm movements.
It is a good mouse and priced right. Hope that this helps.
Product Description

Russ Walkowich's mymac.com Review.......2007-12-30
Over the years, I've used just about every type of mouse out there: Apple's one-button mouse, trackballs, corded and wireless, small and large, two button up to multi-button. I even used the Kensington Turbo Mouse (version 3) during the mid-90's and enjoyed its capabilities and ease of use. Fast forward to the present time and here I am using Kensington's Expert Mouse, the descendent of the Turbo Mouse. How does it hold up?
Out of the box, the Expert Mouse is simple to install and set up. Plug the USB cord into your Mac, go to Kensington's website and download the latest version of MouseWorks, install it and then set your preferences for what you want each of the four main buttons to do, set your click and scrolling speed and the pointer speed and you're good to go. Want to open up an application? No problem, set it up in preferences as to what button you want to use and off you go. Launch a particular URL... set it up and away you go.
The unit itself is designed as 5 3/4"L X 1 1/2"H X 5"W with the end closest to your hand being less than 1/2" in height. Kensington solved this problem of the unit being so sloped by providing the user with a padded palm rest that easily attaches to the low end and slopes your hand up into a more comfortable position. Once you've set up your Expert Mouse, the first couple of hours are normally spent just getting used to the feel and the capabilities of the mouse. The six-foot USB cable should prove to be more than enough for most users to set the mouse up comfortably on their desktop and not feel restricted.
Choosing what button on the unit does what can be an interesting experiment in itself. I found that I changed my first selection of button use once I became more familiar with the unit and discovered that it was far easier for me to utilize the top left button to scroll, the top right button to go back/forward, open in new window; the bottom left button to click and the bottom right button to double-click. The nice thing about Kensington's MouseWorks is that is does work and it doesn't cause any problems with the operation of the Mac, unlike some other software.
I found the trackball to be great, quiet, smooth and easy to use. The use of the trackball to scroll is just fantastic in its ease of use and control, and with the bottom left button set as the click, I'm easily out of the scroll mode and able to move the cursor to where I want and then use the bottom right button to double-click and open a link. The one issue that I did have is that the Scroll Ring just did not seem to work the way it should. I found that no matter where I had the scroll speed set to, in using the Scroll Ring the movement was jerky and at times, I wound up right back where I started from. Utilizing the trackball in scroll mode solved that issue right away but I was disappointed in the way the Scroll Ring just didn't seem to work the way I thought it should. Despite that issue, I would still highly recommend the Expert Mouse to anyone looking for something more than just a plain old mouse.
So to review:
Pro: Easy to use, easy to program, good number of programming options available to the user; use of trackball to scroll was great. Great warranty on the product.
Cons: The one problem that I had was with the Scroll Ring, just could not find a comfortable movement to make scrolling as good as it is otherwise.
System Requirements: Macintosh running OS X or later with an available USB port. Internet connection or CD-ROM drive to install the software.
Warranty: Kensington 5-Year Warranty and free technical support.
Highly recommended!
My Mac rating: 4 out of 5.

Fantastic Trackball But Its Almost Too Smooth.......2007-12-28
I would give it 5 stars but for my needs and preferences I find the new model inferior to the 64214 (and family). Mostly, because I like the weight and feel of an actual pool ball which you can use in the previous models. I also am not a fan of the new scroll wheel placement. That said, this made a great gift and its recipient couldn't be happier!
Trackball works beautifully, the scroll ring, not so good.......2007-12-21
This is my third Kensington trackball and the first of this design. I've tried a number of different pointing devices, and Kensington is still the best of the bunch for my purposes (and for my problematic and sometimes aching hands). The trackball part works beautifully and I love the fact that I no longer have to clean the little rollers. I nicked one star for the scroll ring. It's a nice physical design, but applications respond to it erratically at best, to the point that I've mostly stopped using it. Hopefully, it's just a driver issue and the scroll ring will eventually work as well as the ball.
Remarkably average mouse.......2007-12-20
I used this trackball on a Mac running 10.4 and it performs its basic functions as advertised. You can mouse around the screen and the four click-buttons are large and easy to configure. The optical trackball works.
However, the true disappointment comes when trying to use the scrolling capabilities. As you have read from the product description, the scroll wheel takes the form of a dial surrounding the trackball. This dial suffers from two inhumane issues:
1) The feel of the dial is atrocious. I would have hoped for a slick ball-bearing or smooth-as-silk (SAS) movement. Instead, Kensington delivered an unflattering plastic-on-plastic (POP) feel. Just as you think your fingers have applied sufficient force to overcome the static friction of the dial, some inconsistency in the formation of the POP causes the dial to falter. This leads to the second issue.
2) When you use the scroll dial, your fingers have little choice but to move the trackball. Take a look at the picture and try to imagine this: Suppose you want to make two full revolutions. Your scrolling finger must remain perfectly perpendicular to the dial. In order to make a complete trek around the trackball, you have to crimp your hand. In the event you cannot keep your finger perpendicular, it will naturally swipe against the trackball and move your cursor. What harm does that do? After each scrolling session you must stop to relocate your cursor. In certain applications, this may cause unintended actions.
Lastly, when Kensington moved from their last Turbo Mouse design, they eliminated their quick-launch buttons. Those buttons allowed you to perform virtually anything you wanted with a mere flick of your finger. They are henceforth gone.
At $100 (+/-), this mouse is horrifically overpriced. It's depressing how overpriced this is. I feel pity towards anybody who looks at this mouse online and opts to buy it based on Kensington's description. At a minimum, you should run to your local tech store and try it out in person before you buy it, because then, and only then, will you realize that it's not worth it. This mouse makes me sad.
Nonetheless, I must confess that the 5-year warranty has served me well. My old Turbo Mouse died on me eight times. Yes, eight times. Each time it died I just called up and they sent me a new one. I can only hope that the quality of this mouse has improved over the previous generations. Also, I'd be remiss in my reviewing-obligations if I neglect to mention that the software has never been an issue on my Macintosh systems. It's always been easy to install and configure. I'm not sure if that's a testament to Kensington or Apple, but there you have it. Lastly, the two stars are for it's ability to perform it's core functions.
I'd highly recommend this mouse to anyone who likes overpriced garbage.
Don't bother.......2007-12-19
The Wireless Turbo Mouse would seem to be a good bet, however it suffers from a very poor implementation of the scrolling ring when used on the web. The problem is it should advance the screen smoothly, but it's annoyingly jerky, and therefore continues to be annoying day after day, month after...ect. I called Kennsignton in an effort to tell them my thoughts, and was listened to patiently, but it was a waste of time. The point is, this company had a lot going for it years ago, but now seems to be coasting down hill. Also, the battery needs replacement about once a week, so if you buy this, plan on a recharger and extra set of C cells.

Slow As Molasses.......2007-12-21
I just purchased a brand new Logitech Cordless Optical Trackman and what a piece of poor quality. I have used a rollerball mouse for years and my other one just died...so I read reviews and purchased the Trackman. Slower than molasses...the rollerball will not move up and down and it feels like it drags when I try to move it from side to side. Back it goes to Amazon and I will keep looking....I miss my rollerball mouse!!!
Love this trackball.......2007-12-13
This is my third trackman. Works great with a wireless keyboard. Can be discouraging when doesn't work, but that hardley happens anymore. Usually just means to replace batteries. The only real flaw I've seen is that the long left click button wears out. I am hard on the button but still it shouldn"t wear out that easily. This is what has gone bad in my first two units.
Best Trackball I've ever used.......2007-11-14
This trackball is so much better than the old thumb ball, which wore my thumb out.The wheel is handy for the pointer finger. I had one for a couple years, or more, and this is my second one.
Older is better.......2007-11-03
I bought this for a new computer. I wanted a trackball because of limited space. Unfortunately, there are few cordless ones on the market. This one had nice features and in general worked well. However, the button that controls mouse clicks is mounted so that there is sideways pressure when it is pushed. This means the trackball must be held securely or it will move sideways. My old trackball had a button that was pushed down, and it never moved.
As a result I reinstalled the old cordless trackball on the new computer and relegated this one to the seldom used back-up computer. I'm sorry I wasted the money.
Great Product!.......2007-10-26
Just received the trackball today. At first the ball seemed really sluggish, but after using it for 30 min + it rolls very smoothly. Maybe going from new to used helps it become smooth? The large shape of the product makes it a nice fit for my hand. Many buttons, scroll wheel, right click are nice. I bought the product to replace my Apple bluetooth wireless mighty mouse. So far, I definitely recommend the product.
I have one concern. The software did not run on my Mac. It could be a software issue on my Mac...I tried to go to the website and it still wouldn't run. I'm not too hurt by it, I think the button layout is fine..so far. I do have to say that my Mac automatically recognized it and I didn't even have to "pair" or "connect" it. It just worked!

Nice Features.......2007-12-21
I bought this so that I could sit in my recliner and surf the internet on my big screen. As soon as I plugged the thing in the pc recognized it. I like the shoulder button on the right and the shoulder wheel on the left for the mouse. All the hot keys work, I especially like the forward and back keys for toggeling between websites. The thing seems fairly well built for light to medium abuse. I won't be handing it to my toddler that is for sure. Overall the people who designed this unit obviously took the time to study and ask people what they would like. It seems to be very intuitive in how it works and fits in your hands and sits on your lap, and where the buttons are located. There are cheaper units out there but I am happy I spent the few extra dollars for this one.
Nice keyboard.......2007-12-18
No problems with this unit. The instructions is the only thing that is in need of some revisions.
great keyboard, fixed enter key.......2007-12-15
Just wanted to let people know that the keyboard I got has the eneter key in the normal position. Looks just like the picture, but with that adjustment. Works great so far on both a laptop and the PS3.
Won't sync at all - No instructions - Support is a joke.......2007-12-05
The only part of this product that works in the rf usb dongle which is recognized on my mac and pc but the keyboard itself will not sync. It is possible I am not correctly syncing it but there are no instructions with the keyboard. I tried to get support from the Adesso website but there is no mention of the WKB-3000UB and they have yet to respond to my emails requesting support. I wouldn't recommend this as I have yet to see it work once.
Works well for the price.......2007-12-02
The advertised range seems about right for direct line of sight. I use this keyboard on the second floor and the computer is one floor below, about 10-15 feet away. It's not as good as the more expensive Gyration keyboard, but it works well as a remote control for my entertainment PC.

This produce is a must have for us. If you have shakey hands and poor controal of your hands, this unit will be much easier for you to use than a commond type mouse with the tracking ball on the bottom.
Not bad. . . .......2007-12-18
if you need a cheaper alternative to carpal tunnel syndrome. I, too have used the Expert mouse from Kennsington for as many years as the previous reviewer. I also bought a turbo-mouse. It failed, but was replaced by a Fantastic remake of the Expert, with a spin ring that serves as a scroll wheel (Thank you Kennsington!). But I found the Kensington Orbit Optical Trackball Mouse 64327, despite its high quality, a bit too light weight, literally. It was hard to keep it still during intense use. The smaller ball was also hard to keep from flipping out of its "eye" socket and I found my thumb reaching too high for critical left clicks.
So. . . if you've never used a Kennsington Expert mouse, the Optical Trackball is probably a GREAT choice. But if you're accustomed to the perfect heft, ergonomics and ease on the wrist of the Expert, don't buy yourself short. . . get the Expert.
Trackball mouse elminiates wrist strain.......2007-12-04
When I have a lot of mouse work, if I use a regular mouse I sometimes get wrist pain and discomfort. By using a trackball mouse, in my case the Kensington Orbit Optical Trackball Mouse, I eliminate the pain. Instead of gripping a mouse with my whole hand, I roll the ball with my outstretched middle three fingers. Also, I program the little-finger key to double click, thus eliminating many clicks I would have had to perform with my thumb. When I first got a trackball mouse years ago, there was a definite learning curve/adjustment phase that lasted a couple of weeks. It felt a little awkward. But, that feeling soon went away. Eliminating the carpal-tunnel pain that comes with heavy mouse work is so worth the relatively short time it takes to adjust to using a trackball mouse. I would recommend this mouse to anyone who does a lot of mouse work and want to eliminate repetitive-injury discomfort.
Great Mouse.......2007-11-08
I love this mouse!! The roll ball glides smoothly and I've had no problems so far. I bought this mouse specificaly because of the roll ball, before the mouse I was constantly having wrist pain and since the mouse my pain is gone. I love it!!!

Replacing Already.......2007-12-16
I am getting ready to send this back to Amazon or Fellowes. I have not even had it a month and I have a number of problems. At first it was great. But 2 weeks later it suddenly stopped moving right or moving down on the screen. Bad thing is there is no rhyme or reason, so it happenes at any time. The worst thing I have experienced is it will lock the page in a kind of automatic scroll down position. I cannot do anything on the page unless I use my touchpad or keypoard. Then the Fellowes magically unlocks and I can use it again. I'm bummed because there seem to be few of these on the market...maybe there is a reason. I hope the 2nd one works!!

Great concept - not for Windows Vista.......2007-11-13
The specs don't say it's compatible with Vista but I wanted to try it anyway. It definately is not for Vista. I'm sending it back and trying something else. Lesson learned. It's still a great product though. I tried it on my work PC and it's really neat to use once you get used to the feel of it.
Still Looking..........2007-11-13
What I really liked about the hand held trackball is freedom to sit or stand anywhere(without a table top) to control my computer. I have been checking for other products like it and have only found this trackball. What I hate about this product is it becomes useless after a year or two. This is my fourth Fellowes trackball in about five years. If it wasn't for the short lifespan I would be happy with the product.
Maybe in a few years they may come out with a wireless model. Then I could get rid of the long extension cable that runs across my floor to the couch. If it wasn't for the price I probably wouldn't have bought more than a couple over the years. This is the only pointing device that I have found that I can sit on my couch and play computer games for hours without muscle fatigue in my arm or wrist.

WOW!!! I am impressed!!!.......2007-12-18
This wireless keyboard is better than I could have hoped for. My goal was to sit on the couch and surf the net on my 42" flatscreen TV via my laptop, hooked up to it with an extra-long VGA cable. I plugged the little USB dongle into my laptop, BTW which comes with this keyboard in the box, and was instantly on my way. The little trackball in the upper right-hand corner is nice to navigate with, with your right thumb, as is the mouse switch provided on the same upper-right underside corner, that fits your right index finger. I generally loathe trackballs, but this is quite pleasant actually. I was initially interested in the expensive Microsoft 8000 keyboard, then ran across this one here on Amazon. If this thing ever quits working, I would order another one in a heartbeat, no question! My recommendation is two thumbs up!
Great Value.......2007-09-14
I use this as the keyboard for my living room entertainment center. Although I have the USB RF receiver in the front USB port, I am able to type and mouse as if it were a wired keyboard/mouse even from my kitchen 25 feet away. This is the best purchase I've made for my entertainment center. I love the trackball on the right and the scrollwheel under the left trigger spot. My only complaint is that the RF times out after a short while (5m perhaps), but it comes on with any keystroke (and it still registers that keystroke). When I need to use the mouse, I just hit the shift key and it functions again. This is probably a good feature because it should be saving battery life. I've been using the same batteries for three months and have not had to re-register the keyboard to the USB receiver.
Better than expected for the price!.......2007-08-28
Like other reviewers, I purchased this keyboard for use with a home theater system. Surprised that Sony doesn't offer a Bluetooth keyboard to go with the PlayStation3 (yet), I did some research and settled on this RF unit as the best stopgap solution.
Unlike the other reviewers, though, I have had no problem with the RF signal fading in and out. Admittedly, I don't use the keyboard all that much, but whenever I do I am always impressed by how well it functions. It reliably wakes from sleep and functions as advertised with only occasional missed keystrokes. The integrated trackball is a big plus -- no separate mouse to clutter up your living room coffeetable just for scrolling/navigating.
Your mileage may vary, but at 12-15 feet away from the PS3/TV my unit works like a champ.
While its design is nowhere near as nice as that of the new ultra-thin aluminum Apple keyboard -- and its appearance is not very impressive (hey, its a keyboard!) -- at least it is ergonomic and comfortable to use. The rounded corners are nice, and the keys have a decent tactile quality.
