Have the Model O 2 Wireless. Love the mouse, only annoying thing is it doesn’t turn off when inactive. If I don’t flip the switch to off it drains in a few hours.
With my previous Logitech wireless mice, they shut down when idle so I could go days without needing to charge and didn’t have to remember to physically flip the switch every time I use the computer. If I’m hopping on and off 10 or 20 times a day, this gets tedious to remember.
