Cons: charging convenience, fit
Third-party compatibility was a strength, especially with Apple Watch, Natural Cycles, Strava, and other health platforms.

Cons: subscription value, heart rate accuracy
Third-party health compatibility was praised mainly for making Apple/Android ecosystem syncing easier.

Third-party app compatibility is a strength because the app can share data with outside training platforms, though individual integrations vary.
