Question: Does the scroll button on this mouse also trigger left and right, or only up and down?
Document: I was often right mouse clicking while resting my finger on the button. There was still a "click", but it was just too easy to press compared to the left mouse button. I sent it in to be replaced, and the replacement is somewhat better, though the right button is still easier to press than the left. In my mind they should be the same.Also, even when the wheel is in normal clicking mode, it is much too easy to scroll when middle clicking, and middle clicking takes a lot more pressure than I would like.
I love this mouse. It is standard issue at work, and it is the most comfortable traditional mouse I've ever used. It has a nice slope from thumb to pinky side and smooth but not slippery sides that don't require a tight grip for precise movement. I know some users like the smooth scroll wheel, but I like that there is a button up top that allows you to switch between a smooth scroll and a "stopped" scroll (which I personally prefer).The scroll wheel, in addition to the usual downward-press button also has buttons that can be activated by leaning it left or right.
Although the turning is slightly more clunky than a normal mouse with the button pushed, I think I will always keep it on the hyper scroll anyway. The left and right scroll is also great.I chose a corded mouse. Corded mice are nearly impossible to find in stores now, they are mostly cordless. I have a desktop computer, so there is no need for cordless, and I don't want to worry about the batteries dying. Also, I think corded mice are just a tiny fraction more accurate in its movement when doing graphic design.As with most Logitech mice, it is comfortable to use.
I bought this mouse as a replacement to my 10 year old Microsoft 5 button mouse, first of all because it was a very good deal, second it seemed to have the same features as my other mouse. It is not as ergonomic as the Microsoft mouse, and it has taken me a while to learn the positions of the buttons. It also looks and feels a bit cheaper than my old counterpart. I really like the precision of the laser optics, and the quick scroll button. The software does not give you as many options what to do with the third, scroll button, which I miss, but the right/left scroll feature works a bit better than my old mouse.
That hasn't been the case so far although I'm still quite new to this mouse. There seems to be no inclination to left/right scroll when I depress the button. Also I've found that the button doesn't have to be pressed any harder than on the legacy mice like the MX310 and MX300. Maybe just a tad but still quite comfortable. Setpoint has programming to enable the left and right scroll functions to "do nothing" but I likely will not resort to that.In all I find the M500 to feel comfortable in my right hand (not a lefty), have good weight, move easily, track controllably, and generally a comfortable mouse.
It clicks the left scroll button sometimes when pressed normally, but works 70% of the time. I click at the bottom of the scroll wheel to use the middle click on this mouse, but I'll get used to it eventually.Other than that, this mouse is great. I would have preferred to have the left click button just a tad lower so right horizontal scrolling is just as easy as left scrolling, but that's just my opinion. I also noticed how the wheel scrolls for a few notches on normal scrolling mode when given a good spin.Using the germ magnet mice at school is now a strange experience compared to this mouse.
A click of that small button on the left side of the mouse activates spaces!I have killed two birds with 1 stone! I wont' have to replace batteries on my mouse anymore, and I can activate spaces with my hand on the Logitech Corded Mouse!! Also, I have a scroll wheel that is fully functioning! I am extremely satisfied with this purchase!! (By going to system preferences on your Mac and clicking the mouse option under hardware, you have the ability to adjust the following (on Mountain Lion): Scroll direction, tracking speed (speed of the mouse cursor), scrolling speed (speed the scroll wheel operates on your web windows), double-click speed, and primary mouse button (left or right).
When off, you can spin the weighted wheel and let it go on its own momentum for a while. The stepped scrolling mode feels a bit looser than what I'm used to, but it still works great. My only complaint with this mouse is that the looser scrolling causes me to accidentally scroll while I'm pressing the middle button. It really only bothers me when I'm playing first person shooters because sometimes I'll accidentally switch weapons when I click the middle button. The scroll wheel also tilts left and right if you're looking for that functionality.Pros:+ Feels as solid as any Logitech mouse that I've ever owned: MX 500, MX 700, and the G7.+ The curvier design feels a bit more ergonomic to me.+ Good button placement with back and forward buttons on the left.+ Wheel tilts left and right for those who are looking for that extra functionality.+ Scroll wheel has a free spinning mode.
I now sometimes use and appreciate the feature.2. Using the scroll wheel as a double-click button. Since this was my top priority feature I was apprehensive that depressing the scroll wheel might cause scrolling movement, in addition to the button click function. That also turned out to be a non-issue.3. Adding left & right scrolling to the scroll wheel's function set. I didn't care about this feature and expected a scroll wheel that might wobble when depressed. After all it was being asked to do a lot.
Since the wheel also contains left/right scroll switches, it is very easy to activate them when trying to depress wheel switch.At this moment the vertical cursor is operating normally - I'm keeping my fingers crossed and will update this review in the near future.Update: June 18, 2013As of today the vertical cursor has been operating normally. The wheel button, as indicated above, is still difficult (annoyingly so) to operate correctly on the first try. I've upgraded the review by one star (from 2 to 3 stars).
Answer: Hi, I didn't know the answer until you asked the question. LOL. So I tried it on a Word doc. The answer: it scrolled both left and right, as well. That's not really a motion in my repertoire, since I tend to use the zoom (cntrl + mouse wheel) for navigation. But now that I know, thanks to your question, I'll add that capability to my arsenal. Hope this helps.
