Impromptu review (made it originally for my sister). Amazfit T-Rex 2. Came out in 2022. 🦖 Rugged "military approved" smart watch. Great for hiking. Includes barometer, compass, navigation link, and many technologies similar to Garmin. DOES NOT include the Google Play store, it's for people who like regular watches. Can read cell phone messages but send them. However, battery lasts at least a week. for some people, 24 days if they don't use it much.
