Heart-rate tracking was one of the product’s standout strengths, often matching chest straps or top rivals closely.
There is no cellular or LTE-style independence here; the watch depends on the phone for fuller connected use.
LTE support is available across the lineup, though few reviews deeply evaluated LTE performance itself.
Materials are a sensible mid-range mix of Gorilla Glass, steel accents, and plastic, giving decent quality without matching premium cases.
