Overview
Talking to Alexa from the wrist is the standout feature of this Amazfit band, which pairs with a phone over Bluetooth. It has a silicone strap, a plastic case and a touchscreen.
Choose it for the long battery life and voice assistant in a small band. The limit is that GPS depends on the phone and the listing gives no sensor-by-sensor breakdown.
Who it's for
Everyday activity tracking, sleep and heart rate checks, and sports from swimming to hiking are named in the listing. Runners and cyclists who want routes without a phone should pick a watch with its own GPS.
Pros and cons
- Long battery life
- Alexa built in
- GPS relies on the phone
- Sensor list is thin
- Shape entry looks wrong
Performance notes
A small OLED display with an always-on option draws more power than one that sleeps, so the quoted battery life depends on how it is used. Voice requests go through the paired phone and Bluetooth link.
