I've had a charge 5 for a year. 1 week battery life is the best feature. I don't need all the fancy stuff other watches do. I even turn off GPS because my phone already does that.
I love my Charge 5. I'm glad Google is keeping the series going. Whenever they inevitably sunset the tiny Charge watches and start pushing the big ol' smart watches that don't work for my tiny wrists and have a bunch of features I don't care about, that's when I'm bowing out.
