" ... I tried correcting my posture etc. ... I purchased this trackball after reading they are supposed to be more ergonomic and help avoid repetitive strain injury. ... I have been using this product for a short while now and it has already helped with my arm immensely. ... The trackball is pretty expensive but well worth it for me, and I think it will last a long time. ... It is well made, comfortable to use and very responsive/accurate. ... "
" ... This Trackball was great. ... "
" ... It is meant for those who need easier access to the large and complicated programs that we use for long periods of time. ... "
" ... I have used Kensington track balls for many years and trackballs are my favorite "mousing" device. ... It is heavy enough so that it stays put when in use -- the attachable wrist pad is a beneficial accessory, which I use. ... "
" ... Great for large hands. ... "
" ... No one else makes a trackball quite like this. ... "
" ... My arm has improved since I have been using it. ... "

" ... Great trackball - I liked it so much that I ordered this one for my office, since I've been using one at home for over a year. ... "
" ... I converted to Trackball Mice a few years ago, and this is definitely the best one I've owned. ... "
" ... I can can get more work done without fatiguing my arm since you don't move much, unlike when using a mouse. ... The trackball is pretty expensive but well worth it for me, and I think it will last a long time. ... It was not as bad as I thought it would be to get accustomed to this peripheral and replace my mouse . ... "
" ... This Trackball was great. ... "
" ... Overall, this current model Expert Mouse is the best one I've used. ... "
" ... Just suffice it to say that I will never go back to a mouse or small ball track ball. ... "

" ... The scroll ring is terribly rough, the ball operation not as smooth as it used to be, and the buttons now require more force to make them click. ... "
" ... and one of the buttons just stopped working entirely! ... "
" ... The thing i hate the most is that scroll wheel. ... "
" ... Have to reboot too often, scrolls jerky if at all, buttons don't respond well. ... "
" ... However, the scroll ring is terrible: it seems like it's supposed to be able to spin freely, but there's one spot in every revolution where it seems to get stuck, and I have to move it back and forth in order to get past that point. ... Additionally, the buttons don't work 100% of the time. ... Several times a day, I will click on something, the button will make an audible click, but nothing will happen, like the click didn't register. ... Clicking again will make this work, but it's very annoying. ... "
" ... Not so for the Scroll Ring/Wheel. ... "
" ... I liked having the programable buttons and I like using the track ball but the scroll wheel did not always work well. ... "
" ... Works well but software will not detect mouse, therefore I cannot program the additional buttons. ... "

" ... Great product have been using them every day for years. ... "
" ... I had enough credit card points to get it free, so I bit the bullet after thinking about getting one for a long time. ... "
" ... After 3 months break in it feels smoother and I hardly notice it anymore, but it still grabs a little in some places, this definitely needs improvement in design and/or quality control. ... "

" ... Locks as if the wheel bearing is stuck and needs oiling. ... "
" ... When I first started using it, it felt rough, grainy. ... "
" ... The remainder of the rotation was somewhat "grainy" or rough. ... I dismantled the first unit and some plastic "welds" were hitting in spots, so carefully trimmed them and sprayed silicone lube into the bearing mechanism, which can't be taken apart easily. ... "
" ... A total rip-off! ... "
" ... Ginormous, and heavy. ... "
" ... Sometimes it's really stiff, and sometimes it turns easily. ... "
" ... The only shortcoming is that I tried to remove the wrist rest and it broke off because it was snapped in so tightly. ... "

" ... The large ball is easy to navigate with and the scroll wheel is a dream once you get used to them. ... "
" ... Yes, there is a learning curve . ... "
" ... Forget it, it's easier to use without it. ... "
" ... Works well, but I do prefer the smaller Kensington Orbit Optical trackball, I just seem to be able to use it easier and navigate the cursor with it quicker, but that may be just me. ... "
" ... It works right and you can program the buttons to have different functions easily. ... "
" ... Easy to use. ... Set up, etc. ... "
" ... I love the size of the roller ball, which is bigger than most of the ones you see, because I can use multiple fingers and it is great on my hand. ... Over all I gave it 5 stars, because it is super easy to use, and in addition I like the rotator wheel that scrolls up or down. ... "

" ... Since I was unsatisfied with how the whole mouse felt I ended up returning it. ... "
" ... Unfortunately my desk layout requires a trackball and after 2 Logitech M570's crapped out, I decided to spend a little more on what I thought would be a better product. ... "
" ... I can get used to using a stiff mouse if my muscle memory remembers to turn harder. ... "
" ... mouse flickers too much ... "
" ... Switched the mouse buttons and screen started flickering and couldn't settle pointer in any area. ... The upper buttons are really not programable for good gaming, as I couldn't register them to keyboard buttons. ... "
" ... i pressed all the buttons and now the mouse will not respond and the software doesn't see that it is connected. ... "
" ... I do not believe macOS is the problem, as my Logitech MX Master Wireless Mouse, Large Mouse, Computer Wireless Mouse can be configured with Logitech Options over Bluetooth on macOS - both of them uses 2.4GHz (different protocols) and Bluetooth Low Energy (Logitech branded it as Bluetooth Smart). ...

" ... IN other words, using bluetooth it is only a mouse . ... "
