Score breakdown
HR/SpO2 near a pricier watch; sleep tracking flawed
Reliable alerts; quiet calls, rendering glitches
Several days per reviewer, not measured
Bright AMOLED, readable at midday
No GPS; buttons misfire in gym
Heavy chunky case, flimsy bezel, IP67
Each part is rated on one scale for every smartwatch and band, from reviewers' accuracy tests and measured battery life where they exist, what reviewers found, specs and owner reports. It rates the product itself, not how good it is for the price.
Pros
- AMOLED screen stays readable even in midday sun and the interface feels smooth
- Pairs easily and delivers notifications reliably
- Heart-rate and SpO2 readings came close to a pricier Android watch worn alongside
- Went several days of on-off use without needing a charge
Cons
- Heavy, chunky case; buttons dig in during weight training and trigger menus by mistake
- Rotating bezel feels flimsy and does little
- Sleep tracking stops counting once you wake during the night
- Call voice is too quiet in noisy places and the speaker sounds tinny for music
- Some emojis and scripts don't render, the engine start-up sound can't be turned off, and data sometimes needs a manual sync
-
A flashy, feature-packed budget watch with a bright screen; its heart-rate and SpO2 numbers stayed within 2-3 points of a costlier Android watch, but there was no chest-strap test.
