Verdict: A strong pick for Android users who want a full Wear OS smartwatch without charging it every night. It isn’t compatible with iPhone, so iPhone owners should look at the Apple Watch.
Good for
- Android phone owners who want Google apps on the wrist (Wear OS 5)
- Anyone tired of daily charging: up to 5 days in smart mode
- Runners and cyclists: dual-frequency GPS for more accurate tracks
Skip it if
- You use an iPhone
- You want the slimmest, lightest watch; this is a large 1.5-inch model
