Why buy each?

Suunto Race

Significantly improved heart rate accuracy

The redesigned optical HR sensor on Race 2 delivers far more reliable readings during high-intensity sessions — a notable weak point of the original Race that has been addressed.

Dual-frequency GPS at 55h

Dual-frequency L1+L5 multi-constellation GPS for sub-meter precision in urban areas and dense forests, with 55 continuous GPS hours on a single charge.

1.5" AMOLED, thinner and lighter

The display grows to 1.5" at 2000 nits while the case slims to 12.5mm and drops to 76g — more readable in sunlight and easier to wear day-to-day than its predecessor.

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.
