Logitech Trackman Marble Trackball Mouse

I was a big fan of trackballs but haven't used one in quite a while. Lately, I've been getting very frustrated with my mouse so I decided to give using a trackball again a try again. I'm using this trackball on a PC. Most people who still use trackballs these days want them for laptops so anybody reading my review should keep that in mind. I do generally enjoy using this trackball and it seems well-constructed but the lack of a dedicated scroll wheel can be frustrating. By default Logitech programs the small left button to act as a Back Function and the small right button to turn Software-Enabled Scrolling on and off. I used the Setpoint Software (which is not included and needs to be manually downloaded from Logitech's website) to reverse the order of the small buttons so the scroll option is assigned to the left button which should be the default in the first place since far more people are right-handed than left. Even after you get used to using a button to enable and turn off the scroll function it's still more awkward than a dedicated scroll wheel and Logitech's scroll button doesn't work universally--in some programs and some Windows settings (like the Start Menu) the trackball's scroll option can't be enabled and you need to use the drag option to scroll. Logitech's SetPoint Software also needs improvement which probably isn't going to happen--trackballs were a big seller for Logitech in the Windows XP and Windows 7 days but at this point, they're probably a niche market product. The SetPoint software includes no built-in update option--instead, there's a link to the Logitech web page so you can manually check for an update. The link doesn't even bring you to the product page--you need to search for it. Logitech's website showed a newer build number of the SetPoint Software than I downloaded 10 minutes earlier that included bug fixes. I clicked the download button but the same version of SetPoint that I already installed appeared to download. To verify that it actually was the same version I tried to install it. The Setpoint installer never checked to see if the version already installed on my computer was the same which is standard for pretty much any software I've installed on Windows 10. I got an error message during installation saying the install failed and I should reboot and try again. I rebooted and ran the installer and this time it said SetPoint was installed successfully but there was no longer an icon anywhere to open the program. I ended up completely uninstalling SetPoint and reinstalling it and this time I got an icon in the Start Menu but I ended up with the same out of date build of SetPoint I started with. That might be why Logitech doesn't include SetPoint or provide an option to download it from their website after Windows 10 identifies the trackball but if you want to customize the button mapping I don't know if there's a SetPoint alternative. I strongly suspect that even though Windows 10 is listed as a compatible OS this trackball was made for Windows 7 or 8--which is the compatibility listed for most of the trackballs sold on Amazon. That would explain the problems with SetPoint and also the fact that the software scroll function doesn't work in something as basic as the Windows 10 Start Menu. This still provides basic mouse functions well enough in Windows 10 but if you are scrolling frequently then look for something else because the scroll option included here is pretty lousy. Update: I find this strange but there's a small program someone in the Q&A section included a web shortcut for called MarbleScroll that works much better than the official scroll option included by Logitech. It works everywhere a hardware scroll wheel would work, unlike Logitech's scroll option. It also retains the functionality of a real mechanical scroll wheel within programs, unlike Logitech's scroll option. For example, let's say you open a picture using the Windows Photos program. With a mouse using the scroll wheel makes the picture larger or smaller on your display. The official Logitech scroll option doesn't do anything but using MarbleScroll instead makes the picture larger or smaller exactly like a mechanical scroll wheel does. I like this trackball mouse a whole lot more now but since Logitech doesn't deserve the credit I'm keeping the three-star rating. If you do purchase the Logitech Trackman Marble look at the Q&A section to get the website for MarbleScroll because it's something you will definitely want to use.
