The watch is really good. I bought it because of the built-in GPS and heart rate monitor. It's cheap enough that I'm happy to wear it even while training for weightlifting. Also running, field sports, and kayaking. Good battery life and easy to use. What lets it down is how terrible the official app is -- at least on iOS. The app is required to pair the device. I'd love if there was a way to connect directly to Apple Health and/or Strava.
