The upgraded metal build held up well in regular workouts and swimming with no obvious scratches during testing.
ECG support is a meaningful differentiator, with reviewers highlighting it as a welcome feature absent from some Garmin siblings.
Fit is more divisive because the large case can overwhelm smaller wrists.
The two-case approach helps most users find a comfortable size and fit.
Fitness-tracking accuracy is the biggest split: casual tracking looked acceptable to some reviewers, but others found the data unreliable, especially for harder use.
Workout tracking is broadly accurate, with especially positive comments around strength logging and general training data.
Dual-band GPS was widely praised for quick lock times and strong route accuracy, though one scientific review noted low recording frequency and possible distance issues.
GPS is one of the Venu 4's strongest areas, with repeated praise for tight tracks, fast lock, and stable route logging.
Health tracking looked reliable enough for everyday use in one review, but another found the overall health tracking disappointing.
Reviewers generally trust the health metrics, especially once the watch has enough baseline data to interpret trends.

Heart-rate accuracy is strong overall and often close to chest straps, though a few reviewers saw brief dips or lag.
There is no LTE option, which limits standalone use away from the phone.
Material quality is mixed: the watch uses metal in key areas, yet several reviewers still noticed plastic-heavy touches.

Only one case size is offered, which restricts fit choice.
Both 41mm and 45mm sizes are available, giving shoppers a real choice between smaller and larger wearables.
