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:	Only compatible with standard definition receivers like the D12, R16, H20 thru H24. Also note that if you have an H25 HD receiver or Genie, these receivers are only SWM compatible (you will need a SlimLine SWM dish) and will not work with a standalone 18" round dish.
Question:	Can the Expert side scroll? I use spreadsheets that are really wide and have a lot of columns and need that feature
Answer:	No, the pipe is too small. It requires 2" outer diameter mast. You can use a pipe adapter instead of buying a new tripod if it won't hold a 2" OD pole.
Question:	Does it work on Linux
Answer:	The RG6 coaxial cable is sold separately and does not come with it. I recommend Solid Copper Core conductor RG6 cable with compression connectors on each end.
Question:	does left click result in double click after use
Answer:	Tell you truth, I could never get the damn thing to work at all with my HR54. I finally just gave up and bought a Dish Playmaker for my RV.

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:	How well does it work with Linux
Answer:	I'm using it with Linux right now, and everything works pretty much as expected. I'm using the Unifying Receiver on a Fedora 28 desktop with X and Bluetooth on a Fedora 29 Beta laptop with Wayland. Everything works on the laptop, and everything but horizontal scrolling works on the desktop. I'm not sure if the difference is X versus Wayland or Unifying Receiver versus Bluetooth. Solaar reports the battery status and easily let me pair it with the unifying receiver I already had on the same machine. It lists two buttons that it doesn't recognize, which I think must correspond to the DPI select button and device switch button. Those work, though, so I don't really care that they don't show in Solaar. Bluetooth also reports accurate battery status in the Gnome control center.
Question:	Does the mx ergo have the super fast, gearless “freely spinning” wheel like the mx masters
Answer:	Nope. It has a cogging mechanism and only recognizes changes between the indents.
Question:	Does this have the same crappy microswitches that will cause click failures in mere weeks for which your M570 is infamous
Answer:	I use mine (M570) for graphic design 8-12 hours a day and yes, IT DOES INDEED HAVE CLICK FAILURE. At one time I had one of our IT staff take it apart and make adjustments to the switches, but the problem came back again in a few weeks. REALLY frustrating when trying to drag and drop objects in a layout, or draw, or even getting a consistent smooth performance for merely highlighting text. It's a legit concern. I need to replace my M570 and am looking at the MX ERGO for the very same reason, but the $100 price tag seems hard to justify.
Question:	What does the mx ergo have or do that is worth $60 more than the m570? just a magnetic hinge and rechargeable battery
Answer:	Yes, yes, and yes!!! I didn't not buy this from Amazon because I wanted to get this right away. I went to Best Buy and got it. I have used the M570 and it was quite good. I had an older keyboard so first upgraded to ergo k860, OMG!!!! what a difference.... then I thought I should try the vertical mouse first. Returned this on the next day. Then I looked at the Logitech Master MX 3 because it had the most features..... Returned this to the next day because once you go a trackball, you won't be back to a regular mouse. Then, before I decided to try MX Ergo, I thought I should just keep m570 because it was better than the first two: vertical mouse and mx master mx3 but then I thought it wouldn't be fair to not try MX Ergo. I AM GLAD, I DID!!! your wrist is going to be thanking you for years!!! Love it! The programmable features are awesome! I work from home and this is must to have nowadays.

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.

User questions & answers

Question:	What is the polling rate for this mouse
Answer:	The paper that comes with the mouse says 125Hz. But Perixx Support is saying 250Hz. Please clear this up Perixx.
Question:	Does it use an optical sensor
Answer:	I couldn't certify it, because I didn't take it apart, but I am 100% sure that it does. Most modern trackballs, if not all of them, use an optical sensor.
Question:	Is this the latest variation of the Perimice
Answer:	Yes, We change the DPI from 1000/1600 to 400/1000, so that the tracking is more stable. The silent click also change back to the normal click, so that it has more of the click feeling. With stable tracking performance, we now keep only one glossy ball in the package.
Question:	Description says two balls in box,, 517 ,,are they hidden in mouse or is the extra one loose in box
Answer:	The trackball mouse has only one ball in the box. When we launch the model in 2017, we did add extra one ball in the first 6 months of the promotion. The two ball version was stop at the end of 2017, and it has only one ball version available now.

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:	Is a left handed version available
Answer:	Closest thing is learning how to switch-hit
Question:	The photo shows this as a left-handed trackball, but there is no mention of left-handed in the description. Is it just that the photo is flopped
Answer:	That is a right handed trackball. You use your thumb on the ball.
Question:	is this Bluetooth or USB only
Answer:	It is 2.4Ghz (Logitech Unifying receiver) USB wireless only & includes all needed pieces for operation. It is also very orthopedic & is the only mouse that I, my children, & my grandchildren use. We own 11 of them & all perform perfectly. All were Amazon purchases. The range is excellent. I use it across a 35' room for volume control of videos played from my PC to the TV.
Question:	I has M570 over 2 years, recently have a problem with Left Click...anyone else
Answer:	Sorry this result is late to the subject, but it's from grim experience. I've purchased at least three units which appeared factory sealed. Two of them failed at about the one year mark with the super-fast-left-click error. Seems like a switch wear problem, as if the tiny internal circuit board button cannot rise fast enough before the pressure from the plastic lever-spring plastic part registers another false click. You can defeat this by left clicking at a super fast speed, barely tapping the button. But such activity by the user is truly tiring and annoying. The old model that came before the M570 was clumsy and slippery under the palmrest area, but it was made better.
