The crystal got a nice in it pretty quick.
And the GPS function def wears the battery down very fast. Also I thought it would be able to guide me more as in a GPS map to my destination without my phone. Does the T-Rex 3 pro do that?

Great watch
The watch has been phenomenal and fun to use. The battery life is excellent and last for days easily. I don’t have to charge it everyday like an Apple Watch. It has many apps and the maps for your walks or outdoor exercises is great. Overall I would buy this watch. It has a very large bezel so if you want a compact watch choose differently but I would certainly buy this again.

Great Watch
I love it! The only thing that surprised me was the inability to make or receive phone calls on this watch. Besides that, all other features are excellent.

Amazing warch
I love the watch. Using it for all my training including swimming now. The only issue I have is it locks especially while swimming and I can’t figure out how to undo this as it keeps me from going on to next training sequence such as running. Can’t find the correction in any part of instruction, help. Otherwise this watch does all it says it can do….. love it.

T-Rex 3 - Can it replace my Garmin Epix Pro?
Wearing the watches side by side for two weeks and I'm very impressed! Health data is almost identical. Tracked multiple cycling trips and they match up perfectly. Love the interface and the app, also the built-in Ai with Zepp Flow. Time to sell the Garmin.

Truly great affordable smart watch for outdoorsmen
Was a Garmin instinct person. Had the Trex-3 for two weeks. The watch had 70% battery when I recyit, it lasted 11 days normal use. Slightly differences in BPM, and Heart rate compare to my instinct. Mapping, steps , outdoor walks almost the same compare to Garmin. Have a little trouble seeing the screen while I’m outside under the sun. I wish we didn’t have to download maps to it. Over all I love it!

Amazing watch
I'm so glad I didn't spend a ton more on a Garmin 8. Can't imagine it would do anything this one can't. I'm very impressed with the quality and the fitness and nav features! My son bought one after he saw mine. He's passed as well.

The GPS is extremely accurate, the battery life is outstanding, and the fitness tracking features are spot-on. Whether I’m running, , or training at the gym, the T-Rex 3 keeps up perfectly. It’s packed with useful features for athletes and fitness lovers, and honestly, it’s giving me the best experience I’ve ever had with a smartwatch. Highly recommend it to anyone serious about their fitness journey!

I really like this watch
I got the watch 8 days ago, charged it fully and it is now 65%. I have to charge my Apple Watch every night. I love the battery life. I have used the map/gps on a couple of workouts and they watch tracked them perfectly. The biggest reason I bought this watch was for the map feature on my wrist without having to take my phone out with me. So far I am really pleased!

Favorite MTB watch
Nice display and tracks all the things that I care about and more. To get the same features in other brands it would cost double. A great value at this price.

Too bulky and plasticky
I would LOVE this watch if 1. It would recognize when I am working out at the gym (heart rate increase and notif to tell me « are you working out? + I answer yes and choose the type of workout) 2. Less bulky: the watch is too large and too thick: it doesn’t even fit under my long sleeve shirts 3. Less plasticky. Do a stainless steel option. Nobody does and it would differentiate you nicely.

Amazing Smart Watch!
I have been using the T-Rex 3 for two weeks now after purchasing it. I am still discovering its features. It has so many health and fitness indicators. For example, the sleep metrics include sleep duration, regularity, deep sleep, REM sleep and awake times. It monitors heart rate, hypopnea, and respiration rate. For fitness, it has modes for outdoor running, walking, outdoor cycling, HYPOX race, strength training, hiking, climbing, pool swimming, open water freediving, indoor freediving, ski mountaineering, etc. I play soccer, the mode automatically set the game into two halves. It monitors workout time, average speed, maximum speed, average heart rate, maximum heart rate, distance, calories burned, etc. The feature that stands out most for me is the navigation capability which is usually found in watches costing more than twice as much. Although it does not have built-in maps, you can download them to the Zepp app on the phone and export them to the watch. You can set up a route on the app and send it to the watch as well. The watch can guide you along the planned route. The battery life is also amazing. For my average workout routine, the battery lasts between 10 days to two weeks before needing a recharge. The build is good. It has a stainless-steel bezel and a high strength polymer body. It feels sturdy, but not heavy.

Love the T-Rex 3 for rough & tough weekends
Absolutely LOVING my T-Rex 3 for its durability and ease of use. I use an amazfit Balance for my 9-5, but for my weekends when I run sound for live music venues and perform vocals in my metal band I need to have a heavy duty watch that can take a beating.
