Like I said elsewhere, this has made my ZW 2 so much faster and responsive. Wrist flicks to wake etc are lightning fast and far more reliable. I like the new notification preview a lot better too after setting it to HIGH. The little keyboard is surprising accurate for swipe typing and the draw keyboard is great too after you install it. It's basically the same as the Apple Watch one. Battery life has been much the same as 1.5 for me now I've used it nearly a day. I've lost count of how many times I've tried to open the apps by swiping left like before and changed my watch face instead but that's something to get used to. Like I also said elsewhere the only thing I'm not really liking on 2.0 is that I can't use wrist gestures to expand notifications or flick my watch down toward the floor to Select/OK and click on items unless I'm missing something?
