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:	Where can i find the instructions for this mouse in english? i only received instructions in japanese
Answer:	Not only are there no English instructions I could not find any Japanese pdf version either. What I did find out I posted here https://sites.google.com/site/gregsqna/hardware/trackballs/elecom
Question:	what size batteries does it use
Answer:	AA battery × 1 required.
Question:	Any right handers using it to relieve carpel tunnel and repetitive stress injuries in the right hand (by switching to the left)? If so, feedback
Answer:	Been using the Logitech m570 on right hand + standard Logitech wireless mouse on left hand for years. It's helped a lot with wrist pain. Finally decided to try this Elecom left handed trackball as it doesn't seem like Logitech has any intention of making a left handed m570. Might get the right handed Elecom eventually as well.
Question:	Do you have to use the trackball or will the cursor respond to mouse movement
Answer:	If I understand you correctly. The mouse itself is stationary. This is a trackball mouse. The soul use of this is spinning the ball to move the cursor. I am unsure of any hybrid mice with the features you describe tho it made me wonder myself. You can always keep a regular one plugged in next to it.

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.
