Summary: no drivers included, you have to download it and run the program in background. the ergonomics are bad for me, i have to use my index finger to roll the mouse. very imprecise for what i do.
Pros: reduces carpal tunnel issues, because it's stationary
Cons: trackball is not secure, can fall out and roll anywhere. scrolling has a gritty feel to it, not what you expect from a high priced mouse. the worst problem for me is the top 2 buttons have to be programmed, but they will stop working. also, you cant use a top button with a bottom button. you have to use either the top 2 or the bottom 2. the scrolling worked briefly, then failed in the program i use. the clicking often fails me, i have to double or triple click to get ...
Summary: My Logitech Marble is still working after 15 years of very hard usage through college, university, software analyst, and telecom jobs across 2 countries. Spare yourself the grief and go Logitech Marble Trackball (just bought another one of those today as a backup).
Pros: I bought the thing because of reviews of people who obviously have never tried other balls. It has 4 buttons. Wheel.
Cons: I found out the buttons weren't programmable out of the box, you had to download this horrible clunky program from their site. They have since tuned the program but it was just something that should have been made available long ago. It broke after only 2 years of moderate usage the eye just stopped registering ball movement. The ball is way to big and it,s very clunky made for a giants hand. Buttons are awkwardly placed, I am 6' tall with very long piano fingers and ...
Summary: I purchased this because of all of the bells and whistles, and because it appeared to be comfortable. I loved the ball over moving a mouse around a pad, but none of the buttons could be programmed as the software for this mouse is not compatible with Windows 7. Be sure and do your research pertaining to the use of this roller ball and its compatibility with your particular system!
Summary: Strongly recommend not getting this trackball if you are using Windows 8 64-bit and cannot live with the generic Windows driver.
Pros: Trackball itself is good. The scroll ring feels cheap, but otherwise the device is good. I like the large ball size and the buttons have a quality click feel.
Cons: The drivers for Windows made my system unusable. I had to unplug the trackball, plug in another mouse in order to regain control and get to the place where I could uninstall the driver. I ended up using the generic Windows 8 mouse driver. This limits the functionality of the trackball, and the pointer speed, even when set at maximum, is a little slow with the generic Windows driver. It appears to me that Kensington has for years made really bad trackball drivers and c...
Summary: I want to set the record straight on a couple of issues surfaced on this board. I actually love this device. I gave it one egg so that people looking for disgruntled users would read this. I've been using Kensington trackballs exclusively for over 15 years. The older mechanical ones needed cleaned occasionally and so some may down grade for that. The new laser ball does not have that problem. The scroll ring is great and is not flimsy.
Excerpt: I bought this mouse because Microsoft discontinued the trackball explorer with program specific buttons. This thing is BAD, I use it for autocad, sketchup, photoshop, etc. where you need program specific shortcuts. 1- this stupid mouse won't let you program "enter" as a button!?!? 2- you can't program different buttons for different programs, each time I change programs I need to reprogram the buttons.
Pros: Good weapon
Cons: Inaccurate, Slow Response, Tough To Get Used To, Uncomfortable
Summary: The first had a scroll ring which would get tight, and stick, it seemed to be sort of oval shaped, and would drag on the housing. I returned that one for a replacement. The scroll ring on the second one was easier to turn, but still very rough feeling, and flimsy. I could have lived with that, but now the left click button has started to not respond, despite the audible 'click'. I'm in the process of returning this one as well.
Pros: Ball is very smooth. It was comfortable to use, for the short period I was able to use it.
Cons: The scroll ring is not smooth, feels very flimsy and rough. Left click button on replacement unit doesn't always register. Tried twice to get one that worked well.
Summary: I'm sure that by the end of the day this will all be resolved, but this is extraordinarily frustrating that not only can I not just install the software and go, but I'm going to waste at least an hour getting this resolved. It's a USB mouse, for pete's sake. This isn't new technology. Since everyone else can do it, I'm going to assume it's not that hard for people with experience. Obviously, whoever Kensington contracted this out to has some QA issues.
Pros: None. Doesn't work.
Cons: Downloaded TrackballWorks v1.04 (no software is shipped with TB). The install blue screen'd my Lenovo W510 Windows 7 64-bit. Reboot complains that one of the TBW drivers is corrupt or incompatible. Tried to reinstall TBW, complains I must first uninstall TBW. Tried to uninstall TBW, it complains that it can't find UnKWorks.UNI. Stuck with a dead mouse until support opens in 2 hours. What year is this?
Summary: Product Quality is the lowest for any mouse/trackball I have ever used. I have a Kensington Expert Mouse 5.0 that works better then this thing. Im going to revert back to that one for the time being until i find a replacement. The only draw back to using my E.M. 5.0 mouse is that the top 2 buttons dont work because Kensington wont make updated drivers for it. That seems to be a re-occurring theme with Kensington.
Pros: the only pros would be that this mouse has multiple buttons that can be programed. Thats It! there are other trackball that fit stationary needs and others that have scroll capability as well, so those are not pros as far as I'm concerned.
Cons: The buttons are garbage. Your thumbs need to be so low on the buttons in order for it to recognize that you clicked it, otherwise it ignores the clicks. The left click button actually depresses towards the right, towards the center of your hand making the actual click contact difficult if your hand is move up over the mouse (ie all the time with the provided detachable wrist pad) without the pad my wrist sits on the desk, thus lower on the trackball and it recognizes ...
