I also have the T Rex 2. This watch has better battery life, very rugged for all sports, very good apps. THe GPS acquires super fast. Using it for marathon training, skiing, cycling, hiking. The training tools are very good and helpful.

As a long-time Fitbit wearer, I really like the Amazfit Balance after about a month of wear. Some of the features I am enjoying so far: phone media controls, long battery life, readiness scores, coach, many available workouts, nice free watch face options, loading basemaps into watch, sleep graph.

I like how the app works with the watch. Easily understood diagrams, health advice and AI tools are great. I feel the night breathing and heart monitoring is crucial, suggestions to contributors to possible issues and sleep monitoring is very informative.

I am very happy with the smartwatch and the Zepp app. Since it can share data with Google Fit and Strava I am able to port the watch data across multiple health apps. Along with the PAI score it motivates me to keep moving to hit the required targets to improve my health and by hitting those targets I have seen a noticeable drop in my glucose levels.
