So: two buttons on the side to browse the web (the must)
Two buttons to adjust the speed of the mouse
The wheel (of course)
And right click buttons left & click! (Right squeaks a bit when we go too hard, eg during a game LoL, Strife or more!)
The mouse goes in standby after 8 minutes for the economy of the pile
And finally, when the battery reaches the end of its life, a red light indicates it!
