This watch is BIG! I love it. I was on the fence about it, thinking it might be too big for my small frame and look stupid on me. LOL Several people have told me that it's perfect. Go big, or go home, right? I'm still working thru different settings. The app has more info than the instructions that came with it, of course. I purchased to replace a dead fitbit to track my sleep patterns and heart rate as suggested by my cardiologist. Another plus is that Alexa is built in. Very handy. It's a keeper!
