Top complaints
Garmin Vivoactive 6
- Some units fail or lose connection
Amazon's review summary says customers disagree on reliability, with some reporting it stops working after a couple of months, and that connectivity and durability are mixed, including screen cracks after six months. One Amazon reviewer says Bluetooth disconnects often.
- Limited smart features and apps
Tom's Guide lists limited third-party apps and smart features as a con; there's no LTE option, and no onboard ECG or skin-temperature sensor.
- No altimeter; smart alarm needs work
Without an altimeter it undercounted climbs in Tom's Guide's tests (by about 14 ft against an Apple Watch SE and 34 ft against a Galaxy Watch 7). Tom's Guide found the Smart Alarm's 30-minute window too short and its vibrations jarring, and an Amazon reviewer also calls the smart alarm not great.
Google Fitbit Air
- Automatic workout tracking is hit or miss
Wirecutter found auto-detection unreliable after weeks of use, especially for non-running exercise, and there's no button to start a workout. Tom's Guide says auto-tracking only starts after 15 minutes, and PCMag lists limited automatic workout tracking and fewer workout details as cons.
- No screen, no GPS: data lives in the app
Wirecutter notes you can't get real-time updates without your phone, and there's no built-in GPS. Tom's Guide also lists no onboard GPS as a con.
- Mixed sleep tracking, pairing and reliability reports
Amazon's review summary says sleep tracking and connectivity are mixed, with some owners reporting poor sleep tracking or trouble pairing with phones. It also notes doubts about step accuracy and some units working for only a week. Per Google, Sleep Score and sleep stages are free; the Gemini coach and detailed sleep coaching need the Premium subscription.

If both catches are deal-breakers, start here.
Tom's Guide's best budget tracker: about half the price of a Fitbit, with a bright 1.72-inch AMOLED screen, 159 activity modes and step counts that matched an Oura Ring. Battery fell well short of the 21-day claim in its test, and the app's insights feel less actionable than pricier rivals'.
Its catch: battery well short of 21 daysA third option · #5Garmin Cirqa Smart BandGarmin's $199 screenless band sits between the Fitbit Air and Whoop: it excelled in Wirecutter's distance tests, has a physical button to start workouts, lasts about nine to ten days and gives you all of Garmin Connect's data free. It costs twice as much as the Air, and Tom's Guide found it bulky and slow to dry.
Its catch: twice the price of the Fitbit AirAll 10 comparedSee every fitness tracker, rankedEach one's biggest complaint at a glance, with the full ranking and a 3-question quiz.
