Yes, the mouse automatically shuts itself off between uses and the batteries will last around 2 years. There is a motion sensor inside of it so you would only use the on/off switch when you are traveling with it in your car or in your backpack. Otherwise you would just leave the switch in the on position 24 hours a day.
Plus go to the Logitech web site and download the “Logitech Options“ program so you can reprogram each of the 7 programmable switches on the mouse.

Note: Click on the circles in the mouse diagram in the Logitech Options program to reprogram each of the buttons functions.
I like the scroll wheel down button for “Mute” / scroll wheel left “ Close Window “/ scroll wheel right “ Open Web Page “ google.com
