I love my COROS Pace 2 because of how lightweight is! I have a TINY wrist and it’s not bulky like some other running watches. I like that the GPS is QUICK to connect and has great accuracy, it doesn’t mess-up when running under trees & buildings which is a huge plus. The battery life is BRILLIANT and lasts so long! Uploading to the app is almost instant. The sleep tracking feature is cool too!
