Polar Flow is described as a broad athlete ecosystem with useful website tools, exports, community features, and app support beyond the watch itself.
The software/app offering feels broad rather than sparse, with Garmin Connect on one side and a very large set of apps, widgets, and subcategories on the device itself.
Reviewers consistently like the strap comfort and feel, though one notes the closure can be a bit finicky.
Band quality is mixed: the stock silicone option gets decent remarks and one reviewer saw an upgrade, but another strongly disliked the optional nylon band for drying out and aging poorly.
Battery life is a clear strength, with most reviews landing around five to seven days of normal use and about 30 hours of GPS tracking, plus battery-saving modes.
Battery life is one of the product’s best traits, with repeated praise for multi-week endurance in real use and very strong official estimates across AMOLED and solar versions.
One review explicitly notes that blood oxygen tracking is not offered on the M2 and is reserved for a higher-end Polar model.
Blood-oxygen tracking is presented as part of the 24/7 health suite and framed as useful for respiratory-health monitoring, but the reviews do not deeply test it.
Bluetooth support is strong for normal syncing and sensor use, but not every external accessory behaves perfectly.
Bluetooth support is treated as solid and practical, covering Bluetooth calling and headphone playback without complaints about stability.
Brightness is good enough outdoors, but several reviews call the display dim indoors or in lower light.
Brightness is good overall, with reviewers finding the screen easy to read and in some cases noticeably brighter than earlier models.
The watch feels solid for the price, with a metal or stainless steel bezel paired to a lightweight plastic body.
Build quality is described in unequivocally premium terms, with reviewers calling it very high and consistent with the price tier.
The five-button control layout is repeatedly praised for sports use and generally works better than a touchscreen-free compromise might suggest.
Buttons are generally liked for texture and easy feel, especially in dark or wet use, but one reviewer missed the older, more tactile click feel.
Calling from the watch is widely praised as genuinely useful when the phone is nearby, especially for workouts, daily errands, and hands-free convenience.
Post-workout calorie and energy-source data are seen as informative and genuinely useful for understanding sessions.
Calorie tracking is most useful when tied to rucking and load-aware activities, where pack-weight input and richer workout data help make the estimates more meaningful.
Charging works, but reviewers mention setup quirks such as lining up the charging marks or relying on a dedicated cable.
Charging convenience is mixed: magnetic charging is appreciated, but the proprietary cable is a recurring annoyance for long-term ownership.
Charging speed is good, with one review citing about an hour for a full recharge and another reporting just under two hours from a partial charge.
FitSpark, Training Load guidance, guided workouts, and fueling prompts give the M2 unusually strong coaching support for its price.

The display is functional and easy to read outside, but several reviews describe it as plain, dark, or lacking vibrancy compared with true smartwatches.
Display quality is excellent on AMOLED, with reviewers emphasizing stronger color, contrast, and overall visual punch.
Durability is generally good for daily knocks and swim use, though one reviewer warns the PMMA-like cover can scratch fairly easily.
Durability is one of the clearest strengths, with reviews calling out military-grade toughness, like-new performance after abuse, scratch resistance, and confidence in harsh environments.
ECG support is clearly present and described as able to detect cardiac-arrhythmia issues according to Garmin, though the reviews mostly note availability rather than deep validation.
Fit is secure once tightened properly, and included strap sizing helps it accommodate different wrists.
Overall fitness tracking is good enough for many users, but review evidence still shows some inconsistency in harder conditions.
Fitness tracking benefits from the rucking mode’s pack-weight input, which reviewers say produces a more accurate picture of workouts than generic hiking logs.
GPS performance is mixed but usually competent: several reviews report good everyday tracks, while others document clear misses in tougher scenarios.
GPS performance is consistently excellent, with reviewers calling routes precisely tracked, extremely precise in testing, and accurate even in harder signal conditions.
Health tracking is generally viewed as accurate and useful, especially around sleep and overnight recovery patterns.
Reviewers found the watch’s broader health readouts credible, with one saying the data matched lived experience and another calling the sensor package more accurate than the prior model.
Heart rate accuracy is one of the M2's stronger areas for many workouts, but multiple reviews still recommend a chest strap when precision really matters.
Heart-rate tracking is repeatedly praised, with reviews citing more accurate readings, only minimal deviations versus a chest strap, and near chest-strap parity in running.
LTE is a clear weakness: one reviewer explicitly notes there is no built-in carrier service, so watch calling still depends on being linked to a phone.
Materials are practical rather than premium, combining plastic or polymer construction with nicer accents like stainless steel or mineral-style elements.
Materials are top-shelf throughout the reviewed models, with repeated praise for titanium and sapphire construction.
Menu navigation is learnable and workable, but some actions take too many presses and certain menus feel sluggish.
Menu navigation benefits from a more organized structure, with reviewers specifically liking how key functions are surfaced more immediately.
Music controls are useful for basic phone playback control, but they remain simple and depend on the phone being nearby.
Music controls are functional and direct, including phone-music control from the watch.
The watch does not store music locally; it only controls audio playing on a connected phone.
Onboard media support is strong, with local storage for music and podcasts plus service support for offline listening.
The operating experience is straightforward and athlete-focused rather than flashy, prioritizing practical training use over richer smartwatch polish.
Where the operating-system experience is discussed, reviewers describe the Tactix 8 as faster and more polished than older tactix models.
Outdoor visibility is a reliable positive, with multiple reviewers saying the screen is easy to read in bright conditions.

Long-term reliability is excellent where directly discussed, with one reviewer saying the watch still looked and performed like new after hard field use.
Safety and navigation help are minimal, centered mostly on Back to Start rather than fuller route guidance.
Safety-oriented features show up mostly in dive use, where alarms, gas settings, and warnings add backup protection.
Included wristband sizing options help fit different wrists, though reviews do not mention different watch-case sizes.
Size availability is good rather than one-size-only, with multiple case configurations aimed at different preferences.
Sleep tracking is one of the most consistently praised features, with reviewers often calling it accurate and reliable.
Sleep tracking comes off as dependable rather than lab-grade; reviewers say results matched their own experience and felt pretty accurate over extended use.
Phone notifications work, but filtering, timing, and workout behavior are limited enough to frustrate some users.
Smartphone notifications are treated as a standard strength, with support for alerts across messages, emails, and calendar events.
Smartwatch features are present but basic, covering notifications, weather, simple watch-face options, and music controls without matching richer smartwatch rivals.

Third-party app support is a plus, with reviews specifically mentioning services like Strava and broader export options.
Third-party support shows up through Applied Ballistics plus music-service support such as Spotify and Amazon Music, giving the watch more ecosystem reach than a closed niche device.
The M2 has no touchscreen, so responsiveness on that front is simply not part of the experience.
Touch response is mostly positive, with multiple reviewers calling it responsive or smartphone-like, though one reviewer found the solar touchscreen slightly worse than the prior model.
The user interface is usually described as clear and easy to understand, though still somewhat utilitarian and not always fast.
The interface is generally seen as user-friendly and improved, especially for people coming from older Garmin models or even no smartwatch background.
Value is a major theme in the reviews: the M2 is often framed as a strong sports-and-health buy if you care less about premium smartwatch extras.
Value is the big tradeoff. Several reviews say the watch excels technically, but the steep price narrows the audience and makes the Fenix 8 or cheaper Garmin models more sensible for many buyers.
