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:	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:	Is $489.99 the price or is this incorrect? If correct, good luck with that, I hope you have long term storage for it
Answer:	Well, it's an issue of supply and demand. The product is no longer manufactured, and New Old Stock - which this is - is in limited supply. Most of us who want or need this device will settle for a used or 'refurbished' one for a fraction of that $489.99 price, but sellers of the NOS item are asking the highest price they think they can get - and if you check around, you'll find that this inflated figure (roughly ten times its original retail price just several years ago) is in fact in the ballpark.
Question:	Logictech no longer makes this trackball, so are you willing to pay 10x the orginal price to have one
Answer:	NO, I am NOT willing to pay 10x the original price for this simple obsolete trackball. What kind of greedy ogre is allowed to markup prices like this? Do NOT fall for this thievery. IMHO.◙ Have a happy 4th of July celebration, be careful with the fireworks, have fun, be safe.
Question:	I bought this last year for $80 and I Know this cannot is not a correct price, is this kind of price gouging common
Answer:	Nathan was correct. I had the same issue a few years ago with a Microsoft trackball. They had discontinued it and the only NIB were going for 5 times more than the original price. If the product is discontinued from the manufacturer and new supplies are limited the market will determine the price. It's not much different from someone selling a collectors item that's NIB for much more than it orginally sold. How about the Beanie Baby craze when people would find a rare one for retail and then mark it up 1000% and resell it.
Question:	I paid $30 for this same thing in 2009 and now it is $439??? what's with that
Answer:	Supply and demand i guess. Im not selling the mouse for $439, so i cannot answer for that particular seller. Once an item is "out of production" it changes the supply drastically.

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.
