Strengths and limitations

the5krunner found steadier heart-rate tracking during sustained efforts, with deviations at startup and changes in effort. Some GPS tracks ran parallel to the route; similar total distance does not mean a perfect track.
23 March test; running, hiking and cycling comparisons. Results depend on wrist and route.
the5krunner: T-Rex Ultra 2 heart-rate and GPS tests
In T3's two-week test the watch used about 4 percent battery per day (about 1 percent of that for sleep tracking) and was still at 22 percent after two weeks without charging. The author estimates 2.5 to 3 weeks per charge without frequent GPS use.
Single review and the author's usage pattern; 51 mm titanium unit with no colour stated. GPS and heart rate accuracy were not measured.
T3: Amazfit T-Rex Ultra 2 review
T3 lists offline topographic maps, the flashlight and a light build for its class as positives, and the very large size on the wrist and still imperfect map controls as negatives. It says the mapping is getting close to Garmin's but is not yet equal.
Single review; no side-by-side measurement with a Garmin model.
