I love the weight too. However, the battery life sucked -- last time I had one, kept dying after a week needing a recharge. I then bought a Logitech Marathon mouse and I'm already going 2+ years wireless on a single set of AA batteries. That makes me happy. I like products I don't have to think about charging all the time.
I wish they covered the mice in solar panels like the solar-powered wireless keyboard, or harvested kinetic energy though -- that keyboard is another great Logitech hit if your workspace is near a window -- you never have to charge it.
If you didn't buy that used, you probably should've complained to logitech. My master 2 runs ~1 month on a single charge, and when I see the third light blinking I usually just plug it into my laptop overnight. I've not had to deal with a dead battery in this mouse, ever.
Yeah it was new. Weird. Did you have to install any drivers to get it to power save efficiently? Because I run Linux and don't have any Logitech proprietary drivers installed.
I know I'm comparing apples to oranges, but I own a Logitech MX Anywhere 2S and the battery seems to last forever, even with constant use. It works on any surface, too! The best mouse I've ever used.
