    • Durable and bright
Color: Onyx Black
Review Image by J. G. 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

    • Rugged, easy to use, reasonably priced.
Color: Onyx Black
After using for over 2 months, I can say that this smart watch has more "whistles and bells" than this 68 year old man will ever use, such over 170 sport modes, sleep and health tracking, life coach, etc. I am an avid hiker, and I bought the watch for the mapping features. I download maps of the area where I'm going to hike, and the 6 satellite dual band GPS system gives accurate turn by turn directions, if I get lost. The watch tracks my steps and miles accurately, and the heart monitor is also very good. That's all I want it to do! The amoled face is bright, and large enough for me to use without wearing reading glasses. It is very rugged (although I did buy a protector for the crystal) and I have found that the battery lasts at least 20 days with fairly heavy use. The plastic band is comfortable and the watch looks good even on my slender wrist. I didn't want to spend $400.00 for a smart watch and I am very happy with this one! ... show more

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! ... show more

The media could not be loaded. 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
