    • Best smartwatch I’ve ever owned
Color: Haze Gray
I’ve owned both Apple Watches and Garmin watches, and honestly, the Amazfit T-Rex 3 has become my favorite of the bunch. It offers what I consider the best of both worlds: the smart features and ease of use that people love from Apple, combined with the rugged durability, fitness tracking, and outdoor capabilities that Garmin users appreciate. The only features it lacks compared to an Apple Watch are the ability to take phone calls directly from the watch and reply to text messages. For me, that’s not important at all. I actually prefer having fewer distractions while still receiving notifications when I need them. Where the T-Rex 3 truly shines is battery life. Instead of charging every day or every other day, I can go for extended periods without worrying about finding a charger. That alone makes it far more practical for everyday use, travel, outdoor activities, and workouts. The health and fitness metrics are also excellent. Heart rate monitoring, sleep tracking, stress monitoring, recovery data, activity tracking, and workout metrics have all been accurate and useful. The Zepp app presents the information clearly and gives meaningful insights without overwhelming you with unnecessary complexity. The build quality is outstanding. The watch feels premium, durable, and ready for anything. Whether I’m in the gym, at work, hiking, or just wearing it casually, it looks great and performs flawlessly. The display is bright, responsive, and easy to read even in direct sunlight. What impressed me most is the value. You’re getting features that compete with watches costing significantly more while maintaining incredible battery life and ruggedness. Amazfit has created a watch that delivers nearly everything most people actually need without forcing daily charging or a high price tag. If you’re trying to decide between an Apple Watch, Garmin, or Amazfit, don’t overlook the T-Rex 3. For anyone who values battery life, health tracking, fitness features, durability, and overall value, this watch is an absolute winner. It’s easily the best smartwatch I’ve owned and one that I would purchase again without hesitation. ... show more

    • Good for the money
Color: Onyx Black
Watch is good. Battery is wonderful. Looks good and masculine. Is not heavy for the size. Wristbands are nice. Software wise it does work well. Haven’t tried maps, but everything else works great.

Review Image by J. G.
I switched from an Apple Watch to the TRex. The main reason I wanted to switch was battery life. The Apple Watch at best could get 24-30 hours, but general use 24hrs was my average. I looked at the Garmin Fenix 8 but I really just didn’t want to pay that price. I watched review after review and felt the TRex was the right fit for my needs. Concerns before I purchased: - messaging - calls - no Speaker I have had the device now for about 45 days. Durability - this is a solid watch. I have been doing a full kitchen gut and remodel. I have warn this watch the whole time and it looks like me. No scratches or evidence of any damage. Battery Life - I think confidently 18 days is consist. The first few days I was messing with the settings and looking it over a lot so battery was only 10 days after charging to 90%. I think you could get even more if I turned off notifications and brightness down. Navigation and menus - the OS is really smooth. Very fast to respond. I like the mix of buttons and touch screen. Especially when you have gloves on and such Insights and Health - I think it is far more accurate on steps than my Apple Watch. I wore both watch’s on the same wrist for a full day and I never realized how many non steps my Apple Watch was picking up. I was sitting and typing at my desk. The Apple Watch picked up a nearly 100 phantom steps. The TRex picks up stress pretty well. It notices when I am thinking about a topic that is stressing me, like “is my flooring going to arrive in time?” Or “we only have x hours to complete this before the contractors are here!” Lots of good health habit reminders and such. I am looking forward to getting more use out of them once this project is over. Price, quality, and worry - when you have an expensive watch you worry about damage. It’s not to say I don’t worry about this watch, but when it’s 1/3 or 1/5 of the price of the other watches you looked at, it’s nice to be able to just enjoy it. Lots of compliments on its appearance and screen brightness. A lot of watch for the process The gaps: I do have moments I wish I could do a voice reply to a text or quick reply, but Apple doesn’t allow that. No speaker is a kind of a bummer and I typically don’t pair my headphones to my watch, but that would be nice to be phone free for a run or workout. Overall, I really like the watch. I thought I would miss the Apple Watch integrations, but I don’t. The TRex still has the camera remote and find my phone features. I don’t really notice anything yet that I miss from my Apple Watch that I would say is a “send it back!” Thing. Updates are fast and so far little tweaks will continue to improve it. I would by it again. ... show more

    • I love it.
Color: Onyx Black
I'm pretty impressed with this watch. I had a fitbit and it quit on me, so I upgraded to this. I'm still not used to it yet and the navigation is a little clunky, but thats MY learning curve and not the watch. I tried a few different watch faces, tweaked some preliminary settings. So far so good. Its a LOT bigger than I expected, but it's light and comfortable, I'll get used to that - but it LOOKS like it's built for battle-rattle. The strap is better than I expected, I was planning on replacing it if needed, but that won't be necessary. The app setup was super easy, and the app itself deserves some praise. I was honestly expecting the app to be a little bit half-azzed, but it's actually really slick, coming from the Fitbit, it seems like it has way more information and a better layout. I have it set to show the HB/M live so its constantly sampling and updating, I like that for the curiosity/novelty factor, and the watch face I chose shows the outdoor temp which it gets from BT connectivity to my phone, thats actually really cool. I shut off all the social media alerts and music controls, I don't need any of that jazz buzzing me all the time. Im just interested in the health stuff and the Date/Time. If this thing lasts a couple/three years (and it obviously should with so few charging cycles) I'll be very happy with this. All things considered - quality of the device, the health app, the many cool different watch faces to pick from, the functionality of the phone/text messaging, music/social media/text (not using but you might), IMO its worth the money. ... show more

EXCELLENT EXCELLENT purchase!!! Beautiful watch, tones of features THAT WORK! Lots of accessories available, especially if you buy the watch band adapter for 22mm bands. App is extremely easy to use and very helpful, set up and connection was a breeze. Battery id outstanding. I have EVERYTHING turned on to test it including Always on feature, and 100% lasted 7 1/2 days down to 23% which is when I recharged it. Recharging was slower than my Garmin but still only took about an hour. Workout features and biometrics are really good! ... show more

    • Does everything and does it well. Amazing watch!
Color: Onyx Black
This is quite simply the very best smart watch I've ever owned. It doesn't just beat the name brands, it far surpasses them. I've owned 2 Samsungs, Garmin, Google and a Fitbit. Nine of those even remotely compared to this. I've owned it for about 8-9 months now and it never ceases to amaze me how much better it is than Anything else I've ever owned. Battery life is incredible. I typically get about 3 solid weeks before it needs charged. All the measurements it records (steps, distance, heartbeat, blood oxygen, etc are accurate and precise. It's indestructible and it looks good too. I have absolutely nothing negative to say about this amazing watch. ... show more

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! ... show more
