This mouse has extra features a standard mouse does not. Unfortunately, some are locked behind the "online" version of Logi Options+ such as the action wheel. So if you work somewhere, you best check with your IT department to see if you're able to even use the mouse as company policy could disallow the app. With that being said, you can still customize a good chunk of the mouse using the "offline" version of Logi Options+. I'm still getting used to the SmartShift feel as it feels off to me. At first I thought it was a QC issue to be honest. The nice thing is you can turn it off if you don't like it which I may end up doing so. So 4* when considered the Logi Options+ nuances.
I would recommend this to a friend!

Thank you for your detailed feedback and 4-star rating of the MX Master 4.We’re glad you appreciate its features and the customization available through the offline version of Logi Options+. We understand that features like Action Ring may require the online version and could be restricted by workplace IT policies, so checking with your IT department is a sensible step. SmartShift can take some getting used to, and we’re pleased you can disable it if needed.
Need on board memory. Other than that, all looks good.
