User questions & answers

Question:	can this be used by left handed person...person has NO use of right hand
Answer:	I have an earlier, non-programmable version which I purchased from Amazon in 2003 and it still works like new. I am actually right-handed, but I have always used it with my left hand because that placement is perferable to me. I have used it on both mac and linux operating systems. In either case, it is simple to configure for the left.
Question:	I have this mouse and I LOVWE it! I like that the ball sits on top. Does this come in a wireless version
Answer:	Is there a wireless version that is NOT a thumb rollerball? (thumb arthritis).I am looking for one JUST LIKE THIS... finger controlled trackball... and one that is not $280-$500 as listed here on Amazon.The "wireless" Logitech at Office Max and Office Depot is the Logitech marble trackball ( "thumb" ) mouse. $489http://www.amazon.com/Logitech-Cordless-Optical-Trackman-USB/dp/B00006B9CR/ref=sr_1_14?ie=UTF8&qid=1402505757&sr=8-14&keywords=wireless+trackballhttp://www.amazon.com/s/ref=sr_nr_p_89_0?rh=i%3Aaps%2Ck%3Awireless+mouse+or+trackball+Logitech%2Cp_89%3ALogitech&keywords=wireless+mouse+or+trackball+Logitech&ie=UTF8&qid=1402505574&rnid=2528832011
Question:	Does it work with Linux Ubuntu laptops
Answer:	I'm running Debian Stable (Ubuntu is based on Debian), and tracking/clicking worked right out of the box, including the "forward" and "back" buttons. I used the ArchWiki0 instructions for tweaking the configuration to what works best for me1. 0: https://wiki.archlinux.org/index.php/Logitech_Marble_Mouse 1: https://pastebin.com/A3dCjtJR
Question:	Does the Logitech Trackman have a scroll option
Answer:	In addition to the Setpoint software made by Logitech, I also installed a small program called "MarbleScroll". You can get it here with instructions from its creator: http://www.fewprojects.com/marblescroll-for-logitech-trackman-marble/. Works flawlessly. However, note that there doesn't seem to be an option to have it stay on after restarting your pc, but you can set it up to be part of your pc's startup routine. Easy to Google and do it yourself. After that, the product is perfect.

User questions & answers

Question:	is it windows 10 compatible
Answer:	yes it is
Question:	does it work with windows
Answer:	Yes. Can't remember if I needed a new driver or not, but it works fine.
Question:	Does this mouse work for lefthanders
Answer:	Yes. My husband is left handed and this is his second one.
Question:	what is the difference between models 904-360-0403 and 910-000-806? They look the same
Answer:	They appear to be the same, but 806 is marketed as the "new" model. I couldn't find any difference between them, either should be fine. I have been using a Logitech marble mouse for more than 5 years, and highly recommend it as a person who works with computers all the time. It does have a short time adjustment for non-tech people, but I believe it is an easy transition with lots of benefits. You can set the buttons as shortcut keys too.

User questions & answers

Question:	Does the scroll ring on this mouse have clicks that you can feel while scrolling - when scrolling through a set of images to be able to know that you
Answer:	The scroll ring does have some sort of slight detents (clicks), although I don't know if each click correlates with a singular action, i.e., scrolling from picture to picture in your case.
Question:	Can the Expert side scroll? I use spreadsheets that are really wide and have a lot of columns and need that feature
Answer:	Even better than holding the SHIFT key, you can scroll horizontally ONE-HANDED: Assign one of the additional buttons to activate the SHIFT key using the included KENSINGTON TRACKBALL WORKS software. I recommend using the button opposite your thumb so you can use your thumb to scroll horizontally. So, for those RIGHT-handed assign SHIFT to the TOP RIGHT button, for LEFT-handed assign SHIFT to the TOP LEFT button. This works on Windows and Mac OS X.More Info: http://www.kensington.com/us/us/6498/trackballworks%e2%84%a2-customization-software
Question:	Does it work on Linux
Answer:	Yes. I’ve used this trackball with 5 different releases of Linux Mint going back some years. All 4 buttons will work, but you will have to monkey with your desktop environment to map them to what you want.
Question:	does left click result in double click after use
Answer:	I have a Kensington "Mouse Port/Serial" version (RS232 "COM" Serial or PS/2) Expert Mouse trackball (from the mid 90's) that I bought new all those years ago when I built my Intel 486 DX2-66 PC (66Mhz = 0.066Ghz) and have been using for hours and hours every day on each PC upgrade I've built ever since (currently a i7-4790K !), including audio editing, gaming, web browsing, and more... I still have the original box which says "OS2 Warp" and "Works with Windows 95 and Windows 3.1" and "5 Year Warranty" on it (yes, it's really THAT old!) and all these years later I'm now using it on a 4.0Ghz quad-core PC running Windows 10 Pro x64 with no problems whatsoever! Even after pounding hard on the bottom left button for gaming year after year it just took the abuse and kept on working fine. After about 15 years of that abuse along with lots of hard pressure holding of that same bottom left button for selecting audio segments, manually scrolling through documents and web pages, and so on, it began occasionally either releasing or double-clicking during selecting of audio segments as if I'd released the button when I had not, BUT after sitting overnight it always goes back to normal and doesn't act up like that unless I start doing lots of heavy thumb action with bottom left button holding or pounding again. If I remember to go a little easier on the pressing or don't do a ton of left button holds it can go for weeks before the bottom left button gets quirky again. Also note that it's literally 20 years old, it's been doing that off and on for about a decade now, and it has never been anywhere near as intermittent and downright useless as the Logitech buttons become in less than a year with comparable use. We have Logitech trackballs at work and after the third replacement batch in 2 years they've learned to live with the flaky buttons because the boss feels that $25-$40 for a mouse is absurd and he definitely won't spend the money to buy Kensington trackballs... I'm actually about to replace my 20 year old Kensington Expert Mouse with the new model, only because I need a KVM, my back-lit keyboard is "USB only" (PS/2 Support), USB didn't exist when I bought my now 20 year old Serial/PS-2 Expert Mouse, and although I have successfully gotten its' signals to convert to USB through a (RS-232 COM Port) "Serial to USB interface" and also got a PS/2 to USB keyboard/mouse signal converter dongle to work with it I haven't been able to successfully get either of those converted USB signals to pass through a USB KVM...I started to look for other ways to adapt PS/2 or Serial to USB that claimed to be KVM compatible but I couldn't find a workable solution that would pass through a USB KVM for less than the cost of a brand new Kensington USB Expert Mouse so sadly I think my 20 year old Expert Mouse is about to be retired and an new USB one will finally be taking its' place soon. I hope the quality of today's Kensington Expert Mouse is as good as they were 20 years ago. Time will tell... Also note that my 20 year old Expert Mouse that still works very well uses 2 giant wide metal rollers for the X and Y axis motion detection (that the ball rests on) with photo-led sensor wheels inside to generate the X/Y mouse movement signals, basically over-sized industrial grade versions of the small plastic roller rods the old rubber ball mice used to use (which had to be cleaned when the cursor started getting stuck and I need to clean these maybe once every 3-4 years at the most), unlike the much newer mouse technology of the past decade that uses optical detectors to actually look at the ball and see it move. As a comparison, Logitech once offered a big track ball mouse for a while that looked almost identical to the Kensington Expert Mouse for less than half the price and when I lifted the ball out to check out the rollers it was immediately obvious why the price was so much less. They were tiny rollers just like you'd find inside a cheap old ball mouse! So 20 years ago you got what you paid for, and even 10 years ago it was obvious that the Kensington products were still vastly superior in quality to their competition and based on the reviews here that still seems to be the case.

User questions & answers

Question:	How long is the cord on the Kensington Orbit Trackball
Answer:	I did not measure it, but my guess is that it is around four feet long. I got the trackball for health reasons (wrist, carpal tunnel issues). So I had never even taken the plastic twist off the trackball until you asked the question.
Question:	Does it have a scroll click (middle click
Answer:	Middle click is two at the same time. Given dexterity, it can be awkward. The scroll ring is only a ring. Applications define its smoothness. Some are jumpy.
Question:	How do the buttons feel when clicked? Are they too stiff? Do your thumb gets tired after a long period of use
Answer:	I was previously using a Logitech Marble Mouse trackball which has a much lighter click action than this unit. The overly heavy button springs are my only complaint with the Kensington. My thumb has gotten stronger in the time I have been using it, but long periods of game play do make it quite sore. In conclusion, I like the Logitech for game play and the Kensington for web browsing. Older users will have more trouble adjusting than younger ones.
Question:	Do you have to put too much force on the left button while dragging? Do you have to put your hand in a awkward position to do it
Answer:	Hi, It's more in the pressure it takes to click the button (switch), Most of my mouses and trackballs have hair pin buttons meaning it doesn't take much pressure or finger muscles to click. This one is pronounced, it takes more pressure which over the period of time this adds up. I would send it back if it wasn't more trouble than it was worth to do so. I got it so I could train my left hand to use it. It sits in the closet now.

User questions & answers

Question:	will the kensington trackball work with windows xp
Answer:	In the original Kensington trackballs you could swap out the ball for an eight ball (I had one so equipped) but you can't with their newer models. The size of the ball is different, and as another answer pointed out, these use optical tracking where the originals used mechanical tracking.
Question:	The product photo doesn't show a cord. Is this corded? Thx
Answer:	The Slimblade takes a bit of "training". I use 2 fingers, one to spin the ball, while the other sits on top of the ball to keep it spinning about its axis. Expert Advantage: single finger scrolling and no muscle training Slimblade Advantage: MUCH more scrolling with a single gesture when I give it a hard spin; smoother action for fine control
Question:	They say the lenght and width are 6 w x 7.9 l . their no where near that. why do they measure items by the size of the box
Answer:	Screeching started about 8 months in for me. I tried cleaning, lubricating it, and still get the screeching when I twist the trackball to scroll. It's loud enough that other people in the office ask what that sound is, and it's annoying enough to make me embarrassed to even use the device. Been using it for 9 months now, so far, no it doesn't go away. Kensington support's first recommendation was to "blow some compressed air around the scroll wheel." Considering there isn't even a scroll wheel on this device, it's rather hard to follow their recommendations for fixing the screech. Switching back to a mouse until I get a better response from Kensington support. For a ~$100 trackball, I hope they have a better answer than to clean parts of the device that don't exist. Will update this answer if there's anything worth adding.
Question:	I can't figure out how to scroll with it, can someone give me a clue? I don't want to drag, just scroll down websites
Answer:	The slim blade is a lower profile trackball. Theoretically it doesn't need a wrist rest because it sits closer to the desk. Also there is no scroll ring. Instead you twist the track ball like a doorknob to scroll. I have had both trackballs and prefer the expert over the slim blade. I had significant wrist pain from using the slim blade everyday. The pain became significant after about a month of using it. I never had that problem with the expert with wrist rest. I have since returned to that style trackball. After a few days the wrist pain started to subside. After 2 weeks it was gone. I think the main culprit was the buttons. They are very stiff and require significant effort to depress them. Doing a lot of Photoshop retouching where have to hold down the button while manipulating the ball is what cause the strain injury. Stick with the expert. It's more comfortable to use and I like the scroll ring better than twisting the ball.
