Why buy each?

Garmin Forerunner 165

AMOLED display at entry-level price

The FR165 is the first Garmin entry-level running watch with an AMOLED display — dramatically more readable than the LCD it replaces.

Full Garmin running analytics

Training load, recovery time, Body Battery, HRV status, VO2 max estimation — the same analytics found on watches costing twice as much.

11 days of battery

11 days typical use and roughly 19 hours GPS — enough for most training blocks without mid-week charging.

Xiaomi Smart Band 10

Brighter AMOLED at under $40

The Smart Band 10's 1.72" display peaks at 1500 nits — 200 nits brighter than the Band 9 — making it more readable in sunlight, all for around $40.

21-day battery with health monitoring

Continuous heart rate, SpO2, stress, and sleep tracking — all running for 3 weeks before charging. Seven more days than the already impressive Band 9.

Works with iPhone and Android

Full functionality on both platforms via the Mi Fitness app, including notifications, sleep analysis, and health trends. Bluetooth 5.4 for improved connection stability.
