Durable and bright
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 SpeakerI 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 suchInsights 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 processThe 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.

I amazing this
The Amazfit T-Rex 3 Pro is truly impressive. The AMOLED display is sharp and easy to read in any lighting condition, and the battery lasts a long time I don’t need to charge it every day. It has accurate GPS, offline maps, and over 180 sports modes, which is perfect for anyone who enjoys different activities. Plus, it’s durable, waterproof, and even comes with a built-in flashlight, a super useful detail for daily life. For me, it’s a complete watch that combines technology, durability, and practicality.

Impressive & well thought out smartwatch
The battery life of this watch is phenomenal, lasting weeks rather than days. It has a built in flashlight (super convenient) with 3 brightness levels and even a red light. The rugged styling of this watch is perfect for outdoor adventures but it also can work for the office by a quick change of the watch face – so many options to choose from. This watch is packed with apps and workouts that are easy to use and will help keep you on track for your health and fitness goals.

Sleek
I recently got the Amazfit T-Rex 3 Pro and I’m really impressed. The great quality is obvious right out of the box, and the sleek design makes it look good whether I’m at the gym or at work. It has tons of functionality — from GPS and offline maps to a built-in flashlight and sports modes for just about everything. The battery life is amazing, lasting weeks instead of days. For me, this watch has become an everyday must have, and I’d definitely recommend it to anyone looking for a durable outdoor smartwatch.

Amazfit watches are great
Still some of the best smart watches around. I used to own a lot of different watches from other known manufacturers and now they are in a drawer discarded for lack of use. And in another drawer I have all my amazfit watches. I have many but my favorite are the T-Rex watches. I own the T-Rex 2 and now the T-Rex 3. I am still trying to figure out all the T-Rex 3 features and my review will be incomplete for now but I still like this watch. The battery life is less than my T-Rex 2 but it is still a solid 2.5 weeks on how I use it. I also think that I disabled the map feature because it does not show the enhanced display I saw on the advertisement. But like I mentioned, I am still getting used to the watch. The steps compared to my T-Rex 2 are less but more accurate because I think that my T-Rex 2 was more generous. The workout features are great and have a lot more options. The display is larger and better to look at for guys like me with poor eyesight. When I am at the gym I can see things a bit better through the sweat and tears.The notifications are good but sometimes the delay between my phone and the watch is a bit long. I am still trying to figure out things but so far is a good product and a good purchase for me. And the price was good enough for my budget. The T-Rex watches are durable and I really like them. It is too bad that I only wear one watch because I have plenty of amazfit watches to fill one of my arms. When I think about the other watches I feel bad that they may never see the light of day. But I like the T-Rex 3 because because it has a large display and I can see things a lot better.Overall it is a good purchase for me.

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.

I am satisfied with this favorable investment. The coordinates obtained from this device (in WGS84) for a particular point appear to be nearly accurate according to the standards of my industry software I am using now ..
