THE PRACTICAL PERSPECTIVE
Overall review.
Try the thumb wheel on a real task
Horizontal scrolling can save time in a wide spreadsheet or editing timeline. Check that the applications you use handle the wheel the way you expect.
Decide what belongs on the Action Ring
Start with shortcuts you already use several times a day. Logi Options+ is part of the setup for Action Ring customisation, so check whether it can be installed on a managed work computer.
Make room in your bag
The sculpted body takes more space than a compact mouse. Check its fit in your pouch and how easily your thumb reaches the controls before choosing it for travel.
