ECG was also a limitation: reviewers framed the missing ECG sensor as understandable at the price but still a downside for users who prioritize health metrics.

ECG was viewed as useful for intentional HRV readings rather than full medical-grade detection.

Fit received positive evidence from the light build and smaller-wrist suitability noted by one reviewer.

Fit was split between praise for smaller-wrist suitability in Grit X2 reviews and criticism of the Pro feeling oversized on a small wrist.

Fitness tracking accuracy was generally positive where evaluated, with reviewers describing reliable metrics and good all-sports accuracy in hands-on testing.

Overall fitness tracking was adequate to good, with one scientific review describing broad agreement but not class-leading precision.

The flashlight was one of the clearest wins, repeatedly described as useful, essential, visible, and sufficient for low-light situations.

The screen flashlight was useful in a basic way but criticized as awkward to access or aim compared with Garmin-style torches.

GPS accuracy received a positive hands-on score, with the reviewer reporting very good test results overall despite minor exceptions.

GPS accuracy was broadly positive on land, with most reviewers calling it solid or impressive, while some noted drift, slower acquisition, or poor swim tracks.

Health tracking features were described as working well overall in the BGR review.

Heart-rate evidence was mixed overall: one reviewer was cautious based on prior Polar sensor testing, while hands-on reviewers reported accurate or more reliable workout data.

Heart-rate accuracy was mixed: many found it solid or improved, but interval, cycling, and bursty efforts exposed misses and lag.

Navigation was useful but limited: reviewers liked route guidance for urban use, while noting the absence of full maps and limitations for mountains or trails.

Mapping and navigation were major strengths, but compass calibration, route workflow, missing rerouting, and map detail limitations created friction.

Materials quality was mixed because the watch was rugged, but one reviewer said it did not feel as premium as titanium or stainless steel.

Materials were viewed positively where reviewers noted the premium case and rugged hardware.

Menu navigation was a common weak spot, with reviewers calling sleep data messy, controls unintuitive, and navigation clunky.
