Amazfit T-Rex 3 Pro: A Cautionary Tale of a Budget Watch

Introduction

The Amazfit T-Rex 3 Pro was introduced with grand ambitions, aspiring to knock Garmin off its high pedestal in the outdoor watch market. At a price point of $400, the prospect of obtaining Garmin-like features for a fraction of the price enticed many. However, as I've delved deeper into the functionality and user experience of the T-Rex 3 Pro, it has become evident that this watch falls short in several critical areas, and those shortcomings significantly impact usability.

Design and Display

The T-Rex 3 Pro features a robust design, characterized by its 49-mm rounded octagon shape and a somewhat chunky build, measuring 14mm thick. On first glance, it might have a commanding presence, but it's not the slim and elegant design enthusiasts might expect from a true outdoor companion. It sports a titanium bezel and a nearly indestructible sapphire lens, housing an AMOLED display with an impressive brightness level of 3,000 nits. While that sounds appealing on paper, its dimensions may make it more cumbersome than practical for those seeking an everyday wearable.

Battery Life

One area where Amazfit's offering does excel is battery life; the T-Rex 3 Pro promises an astonishing 25 days under typical usage conditions. This surpasses many competitors, including the Garmin Fenix 8, which only lasts 16 days. Given the multitude of sensors and features packed into modern smartwatches, longevity should indeed be a priority, and here, Amazfit delivers.

Health and Activity Tracking

The T-Rex 3 Pro boasts 24/7 health tracking capabilities, enabling it to monitor heart rate, sleep, and even your stress levels. It includes a variety of sensors, such as a depth sensor for diving, and boasts an AI assistant aptly named Zepp Flow. This assistant acts as a new-age personal trainer and can guide users through a multitude of activities, but its performance under pressure often leaves much to be desired.

A Closer Look: Features and Functionality

However, the hope of accessible outdoor navigation is where this watch stumbles significantly. The device offers offline routing capabilities, a claimed highlight of the T-Rex 3 Pro. It sounds great until you delve deeper. During testing, the route creation often led to error messages, rendering the feature more of a fantasy than a functional reality. Reports indicate that actual mapping is laborious, with slow download speeds for maps, making it impractical for users hoping to set off on outdoor adventures without fuss.

User Experience

The user interface is another contentious aspect of this watch. Navigating screens requires numerous button clicks for tasks that should be simple, dragging the experience down. Additionally, the lags experienced with Zepp Flow can be frustrating; lagging for seconds during simple activities is unacceptable in this competitive market.

Software Limitations

With 26GB of available storage, one would hope that utilizing that space for music would invigorate workouts. Unfortunately, the absence of popular music applications means that offline streaming, a basic expectation now, is unavailable. What's more disheartening is that this watch's notifications bubble incessantly, disrupting the focus one should have during a workout.

Pros and Cons

  • Pros: Impressive battery life, solid materials, extensive health features, and a flashlight.
  • Cons: User interface is clunky, navigation features are buggy, and fitness tracking is often inaccurate.

Conclusion

In conclusion, while the Amazfit T-Rex 3 Pro holds promise with its competitive price point and enticing features, the reality is that many of its functionalities feel unfinished or poorly executed. The intention behind the device is admirable, catering to the budget-conscious consumer wanting access to Garmin-level features. But when weighed against the total user experience, this watch is more of a cautionary tale than a fitness companion.

For athletes desiring a reliable and functional outdoor watch, I would strongly recommend considering alternatives such as Garmin's Instinct series or older Fenix models, which, while pricier, provide a far superior experience without the headaches.
