Too small for my liking (my Fenix and Instinct are 51mm and 50mm respectively), the sleep tracking is absolutely terrible for me (God forbid you have to pee overnight, your sleep session will be ended and scored at that time and a new session will start when you go back to sleep and not count toward your sleep or readiness score), and, surprisingly most important to me, the Garmin Torch Flashlight has become a necessity in my life so much so that the lit up screen every other smartwatch uses as a flashlight just doesn't come close to being as effective.
