What Customers Say

Owners enjoyed the third‑generation T‑Rex for its detailed mapping and numerous workout modes, and they were particularly impressed by the multi‑day battery and 5ATM water resistance. The watch’s rugged design with an upgraded strap stood up to outdoor abuse, and the price is well below comparable Garmin devices. Negatives mentioned include its bulky profile, slightly dull display, and less reliable heart monitoring at high intensity. Some also wished for more refined smart features. Overall, it’s valued by trail runners and climbers seeking affordable navigation and endurance rather than slick aesthetics.
