AmazfitT-Rex 3 Military Smart Watch 48mm, Fitness Watches with GPS (with Privacy), AI, Voice Control, Offline Maps, for Android or iPhone, 170 Sports Modes, 328ft Water-Resistant, Black

So far, after using the watch for a week now, I am impressed. I've used other smart watches and this has been the best so far. Seems some of the difficulties I've experienced with watches in the past are better with this T Rex 3.BT connectivity is better. No issues linking up to my phone. And when loosing connectivity due to distance or such, the watch and the Zepp app seem to reconnect very well. I do not, and have not had to go through any BT reconnect process since my first pairing.The heart rate monitor seems much more reliable than other watches. The sleep pattern and logging of such seems very accurate and reliable as well. As with most watches, lots of functions and apps I'll never use, but the ones I do use, seem to work well.I like the excersize tracker functions. One of the features I never thought about, but once playing around with it, I have found it very useful in incorporating into my routine.I did notice the compass and GPS all seemed to calibrate and function much quicker and with more accuracy with this T Rex 3. I was pleased with that result. The mapping feature is working and kind of interesting. Not a feature I've used before, but can see where it could be worthy of trying.The ability to use phone, SMS and such works well, with replies and messaging working well paired with my Samsung Galaxy.In general, typical features found on this watch all seem to work as advertised. The Zepp app has many, many features which seem to be interesting, but haven't yet played around with. No issues with downloading or pairing or data updates from the watch. All in all, seems like Amazfit and Zepp work very well together.As with most smart watches, the navigation through its apps and functions can be "trial and err", but I find this watch to be very near others and no more difficult while being and very similar to others. The Zepp app can be intrusive with permission requests and such, but always having, and giving the option to allow or deny. All depends on what the user finds useful or not.Watch itself is very lite on my wrist. I'm not a big fan of the band, more like a plastic, silicone band, but works fine, just not my preference. Display is very nice and bright, clear and crisp. Battery seems to be working as advertised as well. Vibration intensity and volume of the watch is beyond sufficient.All in all, very pleased with this purchase and would recommend this watch. Don't have any real downsides to it yet. In using this watch and considering it's cost, I can't image why anyone would spend more for other watches. Seems this watch is very near perfect with all the bells and Whistles anyone would need at a reasonable price.

I love this sport watch, full of features, holds its charge for ages. The display looks amazing. It is big but doesn't really feel as large as its size. Fits great, even easy to get used to when sleeping.I use it for all my workouts and activities, may need a little help with some of the strength training profiles, but works a lot better than I expected for weight lifting. Seems accurate for pulse and ox, steps are pretty spot on. The app is really good in my opinion as well.I do wish it had the BP monitoring enabled, maybe someday.Very happy with this purchase.

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.
