   Feature Packed and High Quality
   Have had this watch for a week and I absolutely love it! It was very easy to set up and linked flawlessly to my Runkeeper account. After several hikes and workouts, the gps is extremely accurate, the heartrate monitor provides valuable info, and there is so much other workout data available!Sleep tracking is making me more aware of how I rest!It is very durable and high quality. No problems seeing screen in full sunlight. I’m on the 10th day since I charged it fully and there is 48% battery left, which is awesome! I can’t believe the functionality of this, as there are so many things on the Zepp app that I haven’t even been able to fully grasp what all is possible with this watch.Highly recommended for the quality and amount of options and functions for the price!

   What is there not to like?
   First of all, I used to work for a major smartwatch company (which will remain nameless) writing manufacturing test software and running the data analytics team. Thus, I was very much involved in the device data set uploaded to the cloud and the creation of device diagnostics, usability, and user preference analytics for our marketing and engineering departments. From this point of view, I was very intimate with all the internal device components and how our devices were utilized by our users.I would have to say that this T-Rex3 watch blows away any of the smartwatches I have seen in my previous company at a reasonable price point. It even has more comprehensive feature set than I have seen on my Garmin Venu 2 which I use everyday for my workouts. I wore both the Venu 2 and T-Rex3 on a long hike and the health and workout numbers were very close. Been using this Venu 2 for 4 years now almost everyday and I consider this to be the gold standard for GPS accuracy.I cannot stress how much battery longevity is a high priority to me as I know many users do not want to charge their devices daily as people forget and it is a hassle. I personally make my smartwatch purchase decision starting with how long the battery will last. BTW, I also owned an Apple Watch in the past and I stopped using it as I would forget to charge it daily, rendering it useless to me.Pros- Excellent battery life, almost 2 weeks using the GPS daily every day for at least 1 hour in myworkouts. I believe the battery can run longer without such heavy GPS usage.- Cost to own. You will not find a better, more comprehensive smartwatch at this price point.- I have proven its GPS and health feature set accuracy- I like that it can capture Beidou GPS signals as I travel to Asia frequently- Large high resolution color screen for my old eyes to see everything clearly- Comprehensive set of watch faces, some free but some you must purchase- Comfortable enough for me to wear 24/7 to enable me to collect sleep data- Most of the settings and features like notifications are pretty standard for today’s smartwatches- Durability of this device to meet military standards suggests it should last…time will tellCons- It is a large watch, but it fits me. 42mm is my ideal size, but some may find it too big.- Very functional design, not the prettiest, but also not the ugliest- Appeals primarily to men which locks out 50% of the market who wants this feature set- Zepp app is average at best. For instance, I cannot track the mileage on my running shoes like on theGarmin app. I still like the Garmin app better.

   Get this now!!!
   If you’re adventurous like me and need watch, get this now!After a few weeks with the Amazfit T-Rex 3, I can say it’s a true powerhouse for anyone who loves the outdoors and staying active. This smartwatch is built tough — its military-grade body, 328-foot water resistance, and very easy to set up mean I can confidently take it with me on water sports adventures, hikes, and any unpredictable terrain.The AMOLED display is a standout. It’s super bright, so I have no issues checking maps or workout stats even in bright sunlight, and the night mode is easy on the eyes when I’m in lower light plus it’s scratch resistant. The battery life is exceptional; with over three weeks on a typical charge and hours of extended GPS, it’s perfect for long weekends away or days when I’m constantly on the move.One feature that’s been a game-changer for me is the one-tap health indicator through the Zepp Health app. It lets me check my heart rate, oxygen levels, and stress in seconds. The variety of workout modes keeps things interesting, and the personalized AI training plans help me stay on top of my goals.The GPS accuracy and offline maps have been reliable, and the built-in compass adds peace of mind when I’m exploring new areas. The watch faces are fun to switch up based on the day, giving the T-Rex a bit of a customizable edge.Overall, the Amazfit T-Rex 3 is a solid companion for outdoor enthusiasts and travelers who want both durability and smart functionality. It’s not just a smartwatch — it’s become an essential part of my everyday routine!

   Very Good Low Cost Option For Smartwatches
   First Im leaving 4 stars just cause I have only had the watch for 3 days. Having said that I really like the watch. It is easy to navigate, the weight is perfect barley notice it. Full disclosure, I only use the watch, weather, sleep, heart rate, blood ox, and step counter functions. I do not use it for work out stuff yet. I am a truck driver so im constantly on the road and get home late. Anyways if your looking for a review to help you decide, I would say get this watch. I have ocd when it comes to making purchases such as this. I have watched all the videos and reviews and this is definitely a solid choice for a smart watch that is budget friendly. It looks good and functions good. So far after three days the battery is at 69 percent. It is suppose to have I dont remember either 10 days or 14 days before you need to charge not sure it will make that, just depends on what you have turned on and what functions you got going. Side note this is my woman’s Amazon account so this opinion is from a dudes perspective. If your a fitness junkie always working out everything I have seen from the videos everyone says this is a great watch for workouts.

   The reason i bought was the battery life. I am getting 14 days with always on Display and 25-30 days with always on display off. Light weight wonderful watch and full of features.

   I only had this watch briefly, but it is great to see a company pushing the technology and software that once only seemed available in watches 4-5 x the price.This watch is a great substitute to the Apple, Samsung and Garmin brands of the world, basically giving you the exact same tech and abilities, for a fraction of the cost.However, don’t expect all the bells and whistles of perfect phone integration, compatibility with thousands of apps nor the ability to phone home with this brand. These are the concessions you make by paying far less, for an equally capable, rugged, well polished watch, without a thousand dollar bright shiny name on it.It will still jump out of a plane skimming the stratosphere with you, while plunging into the deepest depths of the ocean with you, and tell you the time and possibly your heart rate while doing so. It just won’t make you feel guilty for overpaying for the privilege of having a great watch on while doing so.It runs apps beautifully, and gives you a nudge on the arm every time someone uploads a family portrait or lunchtime selfie, and will let you know when your boss is calling to find out where you are. It just won’t say that the call is brought to you courtesy of Apple, or Samsung, or Garmin. And that’s probably worth saving a few $$$s for.Highly capable, highly recommended watch.

   Amazfit , please fix this with the next update.I was walking and the “Speed” data was showing half my actual speed, the real speed should be the displayed data X 2. If we do the math, the image I provided doesn’t make sense as the speed displayed was way to fast for a walk. I have not done the other workout apps yet ,but i hope they are calculated the right way.Other than the mentioned, really happy with the purchase, Thank you! 🙏🏽
