Full review
Longer notes from the same comments we summarized above.
What people reported
Owners frequently highlight the long battery life of the Amazfit T-Rex Ultra, with some mentioning it can last for weeks even with advanced features like Always-On Display and continuous heart rate monitoring. For many, this makes it a strong alternative to more expensive watches from brands like Garmin. The GPS accuracy is generally seen as good, with some noting faster locks and slightly better performance compared to previous models. The user interface (UI) has also received positive comments, described as more "natural and logical" and well-implemented, making the watch feel intuitive after a short period. The watch features a rugged build, with discussions around a titanium case and sapphire glass. A metal piece on the watch, initially a point of inquiry, was clarified to protect the altimeter/barometer opening and does not affect water resistance.
Problems people mention
Despite its strengths, several owners expressed concerns about the Amazfit T-Rex Ultra's mapping and navigation capabilities. Some wish for better integration with services like Strava and TrailForks, and find that maps need Wi-Fi for downloads. Users specifically mentioned desiring full-color contour maps and clearer offline navigation options, especially for long trips in remote areas. There are also mentions of limited memory and slower download speeds for maps and routes. Furthermore, heart rate (HR) sensor accuracy is a recurring concern across Amazfit watches, including the T-Rex 3 Pro (a similar model), with some users reporting inconsistent and indecisive HR data compared to chest straps or other brands. Some owners also find the watch's price point to be high for the features offered, questioning its value compared to cheaper or more established premium options.
Where owners disagree
Owners have mixed opinions on the value proposition of the Amazfit T-Rex Ultra. Some consider it an excellent option, offering flagship battery life at a fraction of the cost of competitors like Garmin. Others, however, feel the price is too high given certain limitations, particularly in advanced navigation and app integration, referring to it as a "piss-poor offering" for the cost difference. There's also some debate regarding screen size, with one owner considering an upgrade to a larger T-Rex Ultra 2 from a 44mm T-Rex 3 Pro due to feeling the screen was too small for their wrist.
Who it's for
The Amazfit T-Rex Ultra is best suited for outdoor enthusiasts and athletes who prioritize exceptional battery life, a durable, rugged design, and reliable GPS tracking without the premium price tag of some competitor watches. It's a strong choice for those who appreciate an improved user interface and don't require the most advanced, fully integrated mapping and navigation features or absolute top-tier heart rate accuracy. Buyers should be aware of the potential trade-offs in mapping capabilities and heart rate tracking if these are critical needs.
