Incredible Rugged Sports watch with Smart functionalities

Functionality and Battery life is top notch. Workout detection and GPS accuracy are great. Better than Galaxy watch 7 in all aspects. There are few glitches here and there, but not noticeable in everyday usage. Used it on thru hike in sub zero temperatures with Adaptive GPS turned on and it lasted for a week without any issues where my Galaxy watch died in half a day. AOD and Screen auto wakeup is better than Galaxy Watch. Looks solid and rugged. No BT connectivity issues faced. The screen is bright enough in outdoor for regualr activities as well as navigating with GPX files.Issues:This doesn't have NFC enabled to activate Contactless payments via NFC, but not a deal breaker.Cannot zoom or move in the map while navigating with GPX files.UX for GPX file based offline navigation could have been better.This device resolves the biggest issue of charging the watch everyday. Highly recommended!

Superb watch for fitness lovers

One of the best smart watch of segment. Rugged built, nice looks.Performs flawlessly during work outs. The data measurement is also accurate.I have just shifted from samsung galaxy watch 6 to this watch and am just amazed with the features provided and the battery management. I feel samsung should learn from amazefit.

Incredible Battery and Solid Performance!

I've been using the Amazfit T-Rex 3 for over 20 days now, and I am thoroughly impressed! This watch is an absolute beast.Right out of the box, the build quality feels rugged and durable, exactly what you'd expect from a T-Rex model. But the real star of the show for me has been the battery life – it's phenomenal! I'm genuinely getting 20+ days on a single charge with my regular usage, which includes daily workout tracking and notifications. This is a game-changer compared to other smartwatches I've owned.Beyond the core tracking, I'm really satisfied with the range of features this watch offers. From the various sports modes to the health monitoring capabilities, it has everything I need and more. The display is clear and easy to read even in bright sunlight, and the interface is intuitive to navigate.If you're looking for a rugged smartwatch with incredible battery life and solid, dependable performance for fitness tracking and daily use, look no further. The Amazfit T-Rex 3 has met my expectations. Highly recommended!

Amazing for Fitness and tracking health

Its an absolutely amazing watch with important stats for fitness. It records my workouts and also tracks my health using the different sensors.I upgraded from an Mi Band 4 and the difference is truly amazing. It looks and feels premium and is a valid competitor to much more expensive watches like Garmin.It lacks call functionality but you can still use it if you pair your earphones to the watch. The touch screen is super smooth and easy to use. It also feels lightweight and comfortable and the strap fits comfortably against the skin. Youncan sleep with it comfortably although it takes a day or two to get used to the weight.The only con is that if all the sensors are kept active it does not last more than 10 days. Also most of the watch faces are free but there are also some that need to be paid for. I have been using it since a month now and I feel its an amazing companion that learns from you and also tries to keep you fit

Battery life less than 10 day when used very less and in battery saving mode.

The battery life is falsey marketed It hardly lasted 10 days with very less use that to new watch with time the battery life will be Just 4-5 days i think. They marked 27 days which is completely miselling. A d other features are same as 3-4k watch not worth 20k also the accuracy of swimming and running on treadmill is not perfect.

Mind blowing purchase

Amazing device, I was using Apple watch 8 and switched to trex 3. I have trex 2 which I used 3.5 yeast and still working without any issue. That was the reason to upgrade t rex 3. Brighter display, rigid built quality, unbeatable battery backup (especially when it compare with apple watch 8). There are many new features and technology introduced in trex 3 when it compared with trex 2, also physical size increased and this watch give you that gshock impression on hand.

Amaze fit T-Rex 3

I recently purchased the Amaze fit T rex-3 Smartwatch, and I must say, it has exceeded my expectations in several areas.First and foremost, the build quality is impressive. The materials feel durable and well-constructed, giving the watch a premium look and feel. The sensors are excellent; they provide accurate readings for heart rate and activity tracking, making it a reliable companion for workouts and daily activities.One aspect that I found a bit challenging is the strap length—it tends to be a little long for my wrist. However, I would appreciate it if the manufacturer offered an extra strap option, perhaps in a medium size, to accommodate different wrist sizes better.The touch response is another highlight. Navigating through the features is smooth and intuitive, allowing for a seamless user experience.Overall, the T-rex 3 Smartwatch is definitely worth the money. With its solid build quality, excellent sensors, and responsive touch interface, I would recommend it to anyone looking for a functional and stylish smartwatch.
