Compare Polar Vantage M2 vs Garmin Forerunner 165

Cross-platform compatibility was positive, with solid app operation reported across Android phones and an iPhone.

Customization was limited aesthetically, though reviewers appreciated being able to adjust watch views or remove unwanted sport profiles.

Customization was a strength, from watch faces and widgets to activity screens and data pages.

Display quality was functional and sometimes praised for contrast, but reviewers also called it dull or not very vibrant.

Display quality was a standout strength thanks to a crisp, vibrant AMOLED screen, though one reviewer still preferred MIP for always-visible use.

Durability had limited positive evidence, with reviewers reporting a tough build or no scratches during use.

Durability was reassuring, with reviewers reporting no concerns and even real-world abuse without damage.

Fit was mixed to negative where clasp placement or the need to cinch the band tightly reduced comfort.

Fit was strong for many wrists, with secure wear and little slipping, though the single case size remained a caveat.

Workout and fitness totals were praised when reviewers compared post-workout results or treadmill distance estimates against other references.

Fitness tracking accuracy was praised for broad data quality and even strength-training rep counting in testing.

GPS feedback was mixed: some reviewers saw quick locks and accurate routes, while others reported drift, slow acquisition, or merely average GNSS performance.

GPS accuracy was one of the strongest themes, with most reviewers finding reliable tracks even without dual-band GPS; a few dense-terrain issues remained.

Reviewers described the Forerunner 165 as having reliable sensors and detailed data collection for general health and fitness tracking.

Reviewers disagreed by sport: several found heart-rate readings accurate for runs or daily use, while others said wrist readings could drift and recommended a chest strap for trustworthy training zones.

Heart-rate accuracy was generally praised across runs, rides, and intervals, with only occasional optical-sensor lag or spikes.

Mapping and navigation were limited, with back-to-start viewed as better than nothing rather than true navigation.

Mapping and navigation were useful for breadcrumb routes and GPX/course following, but the lack of full maps was a repeated limitation.

Materials quality was mixed: the bezel could look premium, but plastic construction and scratch-prone lens material drew criticism.

Materials quality was mixed: plastic kept it light and affordable but felt less premium.

Menu navigation divided reviewers: some found it easy and logical, while others said common settings required too many button presses.

Menu navigation was considered intuitive after a short adjustment period.

Music controls were criticized as unintuitive during runs.

Onboard music storage drew split views: handy or smooth for some, but tedious and poor value for others.

Operating system experience was described as utilitarian rather than polished, with functional fitness-first behavior but little mainstream smartwatch flair.

The operating experience was familiar and straightforward for Garmin users.

Outdoor visibility was widely positive, with multiple reviewers saying the screen was easy to read in sunlight or outdoor use.

Outdoor visibility was excellent in direct sun and bright conditions.

Pairing reliability was mixed: external monitor pairing was easy for one reviewer, but sensor compatibility and syncing were criticized elsewhere.

Pairing reliability for headphones was described as generally solid.

Recovery insights were generally valued through Nightly Recharge and training-load context, though one reviewer found the training-load indicator too cautious.

Recovery insights were useful but clearly limited versus higher Forerunners, with some reviewers calling out missing readiness/load tools or odd recovery estimates.

Reliability had limited positive evidence from a reviewer who expected the watch to perform well across many sports.

Reliability was praised in workout use, with one reviewer reporting no issues with stability.

Running power support was praised for external STRYD-style support and native handling, despite the lack of wrist-based power.

Safety features such as LiveTrack were valued for sharing location during activities.

Size options were limited because the watch comes in only one size, though one reviewer liked the in-between fit.

Sleep tracking was mostly viewed as useful and directionally accurate, though one reviewer reported a poor night that the watch missed.

Notification support was consistently limited: reviewers liked that alerts appear, but complained about filtering, activity use, or too many phone buzzes.

Smartphone notifications were described as reliable and easier to read on the AMOLED display.

Smartwatch features were a clear tradeoff: reviewers considered them useful but limited compared with general-purpose smartwatches.
