Questions about this item

Will the silicone wrist strap need replacing after daily wear?

The sporty silicone strap is included and can be swapped if it wears out; no proprietary tools are required.

What limits battery life during continuous all-day use?

The 220 mAh cell is rated for less than seven days, so heavy Bluetooth calling and constant heart-rate tracking will drain it fastest.

Does the aluminum-alloy case get hot during non-stop Bluetooth calls?

The case stays at skin temperature; the low-power design and 5 m wireless range keep heat negligible even during long calls.
