Why buy each?

Amazfit Band 7

18-day battery at under $50

18 days of typical use with health monitoring — nearly 3 weeks without charging, far beyond any smartwatch competitor.

Alexa built-in

Ask Alexa for weather, timers, reminders, and smart home controls directly from your wrist — unusual for a sub-$50 fitness band.

PAI health scoring

Amazfit's Personal Activity Intelligence score aggregates your daily activity into a single 0–100 health index, guiding you toward optimal activity levels.

COROS Vertix

140 hours of continuous GPS

No other GPS watch currently on the market delivers 140 hours of GPS tracking — enough for most ultra-endurance events and multi-day mountain traverses.

5-satellite dual-frequency system

GPS + GLONASS + Galileo + BeiDou + QZSS with dual-frequency reduces error in challenging terrain to near-meter precision.

Sapphire glass and titanium case

Military-grade scratch and impact resistance for the harshest environments: extreme altitude, cold, and sustained physical stress.
