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:	How do you scroll with the Orbit Wireless Mobile Trackball
Answer:	There is a touch pad on both sides of the trackball that you swipe up or down to scroll. The positioning of the touch pads make it so I can use this mouse with either hand. The only caution I have is that you do not touch the top of the mouse while you are operating the trackball. I have small hands, so when using the trackball with my right hand, I usually put my thumb on the left button, my index finger on the track ball, the middle finger above the touch pads on the mouse where it can easily be put to use on scroll pad, and my ring finger on the right button. I invert this position when I am using my left hand.
Question:	Would you please tell me the length,width and depth. Also from the size from the wrist area to the ball. Thank you
Answer:	Depth = 1 1/2", Legnth approx 4", width = 3 1/2" down to 3 1/4", Wrist area to ball is approx 3". It works well, though is only prefers batteries with a stronger strength to them.
Question:	Has anyone figured out how to disable the scroll ring? I don't see how to do it in TrackBallWorks. maybe a device modification
Answer:	The scroll ring sensor can be disconnected with a few minutes work. Switch off the trackball device and push out the red trackball. I removed the batteries. With a tiny, thin screwdriver pry up the sensor ring (the flat black ring around the red trackball when it's installed). The sensor ring is one fairly sturdy piece. Take your time, attacking at several points, using more than one screwdriver, and you will get the sensor ring out. I did it without scratching the trackball device. At the front of the sensor ring is a ribbon cable. Pull the ribbon cable out of the sensor ring cable connector, fold the cable up and stick it down into the trackball body, then reassemble. It looks and works great. Wear safety glasses! You assume all liabilty for your actions; this is an information-only story how I did it. I like the track ball a lot now that it no longer causes random stuff to happen at random times. If you have mini security allen wrenches for disassembly, you can take the bottom off and likely reach the other end of the cable.
Question:	Is there a way to get scroll click or middle click results with this mouse
Answer:	Yes, definitely. I configured mine to perform middle-click whenever I press both the left and right buttons simultaneously. I had to download Kensington' Trackball Works driver software to get this functionality in Windows 8.1.
