THE PRACTICAL PERSPECTIVE
Overall review.
Check the fit before you choose a size
The standard model has a shorter body than the M650 L. A fingertip grip may suit the smaller shell, while a larger palm may want the extra length of the L. Make sure you can reach both side buttons without shifting your grip.
Pick the connection that suits your laptop
Bluetooth leaves the laptop ports free. The included Bolt receiver is useful when the computer has an available USB-A port and you prefer using the receiver.
Use the side buttons for tasks you repeat
Back and forward are handy in browsers and file managers. If you want application-specific shortcuts, confirm that you can install Logi Options+ on your computer.
