5.0 out of 5 stars A great replacement for Apple Watch
By David on November 17, 2020
First and foremost, I use iPhone and I own a Apple Watch Series 3. Therefore, any smart watch I look at must compare to that combination. I also think that Apple Watches are ridiculously over priced for the functionality they provide. Next, the battery life for a $400+ Apple Watch should be more than 24 hours - I think it is criminal that Apple cannot conceive of a design and OS that can make the battery in a 44mm watch last longer than one day! My "smartwatch" journey actually began with Fitbits several years ago. But there was always connectivity or sync issues between the Fitbit and iPhones. My wife still wears a Fitbit, but she still has connectivity issues - even with the latest version of Fitbits. I also tried the Samsung, Garmin, and others - and again similar situation. Connectivity issues, especially with the Samsung, that would cause the watch to forget it is attached to my iPhone. This was especially true when I would leave my cell behind to run to the mailbox and when I got back I would have to re-setup the watch to my iPhone. I also did not want to pay another $200+ for a watch, I wanted something cheaper. So my requirements for this watch looked like this:

- Less than $200
- Designed for the outdoors (walk, run, hiking, swimming, etc)
- Integrates well with iPhone
- Get all notifications consistently
- Do not need to make or answer calls on my watch
- Do not need to make text responses on my watch (my responses are usually more than three letters or an emoji)
- Battery life longer than 24 hours.

Seems pretty straight forward, but Fitbit, Samsung, Garmin have all failed miserably at this simple list of requirements. I found the Amazfit T-Rex last year and my initial thought was it was a cheap Garmin knockoff that will not perform any where near as good. For me, nothing could be further from the truth. I got this a few days ago as a present, because I refused to spend the $130 on something I was convinced was a waste, even though it had some really strong reviews on Amazon and on the web. Here are my impressions of the watch thus far:

Initial Day:
The box the watch came in made me feel as if I had bought an Apple Watch - it was that good. Well organized and familiar. The watch reported a 61% charge on it when I took it out of the box - so I began the setup. The QR Code setup was both fast and easy with the iPhone. I had already downloaded the Zepp app from iTunes so my iPhone was ready. As with most electronics, the watch spent the first hour or so downloading and installing updates and other things - again, zero effort on my part. The usual questions about allowing location services, integration with Apple Health, etc. were next. Then the watch was ready to go! I played with the watch and the app for the next few hours. I will say that the software is not the most intuitive design. I found settings, then wanted to go back and forgot where they were and couldn't figure out how I had gotten to them in the first place. That for me is the biggest complaint about the watch so far... and that is pretty good considering everything else. The watch was down to 54% by the time I had stopped playing with it, so I decided to put it on the charger and see how quickly it charged. It went from 54% to 92% in under an hour.

First Full Day:
So the next day was going to be the first full day test. It starts with the sleep function, When I went to bed the watch was at 87%, when I woke up - it was still at 87%. I then went for my morning walk and used the walking feature to monitor it. The watch did fantastic! Did everything I expected and when I got home to review the walk in the app, I was extremely happy with the reporting. The app excelled in this area, its UI reminded me of the Garmin. Tracking my pace every inch of the way. Heartrate, distance, direction, everything you could want - it was awesome. This is where it basically left the Apple Watch behind. Next, notifications - this was an area of particular concern for me because this is where non-Apple products tend to fail. I got every single notification, phone, text, email, apps - everything. Never missed a beat. After a full day of pings from email, calendar, etc. my battery had dropped to 84%. I had lost only 3% battery in a full day. If this was my Apple Watch, it would be on the charger right now. Based on just this alone, I calculated that I should get about 34 days out of a single charge - AMAZING!!! I will continue to test the watch and update to see if my prediction holds true, but so far this has been the best "smartwatch" I have ever owned.

UPDATE #1
Ok, now I have own the watch for over a week. The honeymoon phase is over and I have tested in various scenarios to see what the implications.

- Always On
Like all watches of this type there is a "Always On" option. However, I found this one to be disappointing. The watch face is not the primary - it seems to be a watch face just for always on, which I do not like. I want it on all the time with the watch face I have set, not showing something else. So for me this is not as good as my Apple Series 3.

- Wrist Lift Activation
Again, like "Always On" - there is an option that as you lift your wrist, it activates the watch. This works, but not as expected. On my Apple watch it worked, but sometimes required a double lift to make it activate. The T-Rex is super sensitive, even for normal settings. As I drive and I turn the wheel, it activates; if I watch briskly, it activates. So it is a bit too sensitive and with that comes battery drain. Based on the usage in the first few days I expected a 20+ day battery capacity. This feature on normal setting knocks it down by half - so now 10+ days. Which is still huge in comparison to Apple. But something to consider if the longest battery life is a goal for you.

- Notifications
This was an area of huge concern for me considering this is not Apple or Android based watch. I am happy to report that all the notifications work the way i want.

- Functionality
I am still extremely pleased with the functionality of the watch. I believe you will see several pros/cons on the accuracy of things (like sleep, hear rate, etc.). I have found that it is good, but not the most precise device in the world. If precession is your focus, then you should not have an expectation of spending less than $200 for it. For this watch I am going for the 90/10 rule - being that its 90%+ accurate; and for me it has been 90% accurate for all the things I have been looking for: sleep, heart rate, pace (walking/running), activity level).

- Software / UI
I am still find this to be a quirky and somewhat confusing. I think there are several opportunities to improve, and as they sell more products, I think this should improve - or it better! :)

So overall I would give this a product a 4.5 out of 5 due to the software/UI issues. The watch itself performs as advertised and meets all my needs.

4.0 out of 5 stars Well done
By Jason Spicer on June 29, 2020
Very nice watch. The band has a little flex and is very comfortable. The watch seems very sturdy. Screen doesn’t smudge and seems very robust. Very attractive watch. Screen faces are very clear and look nice. Wish there were a few more options. The watch connection to bluetooth on the iphone can be a little glitchy and slow at times. BUT I have had the same problem with fitbits and Garmins. The watch corrects itself quicker than Garmin or fitbit though. The hardware seems top-notch. The software needs a little improving. That’s why it is a 4-star review. They have some kinks to work out but only very minor. And the sleep tracking seems to be the only thing that sometimes is not accurate. For instance it has a hard time calculating REM. I wear a whoop strap as well and the sleep data needs cleaned up on the t-rex. But the GPS and heart rate data are pretty spot on when compared to Whoop and Garmin. I am very particular and I would say I am very happy with this purchase. 1/3 the price of similar smart watches with equivalent performance and probably better hardware.

Reviewed in Canada on October 4, 2020
For the price it is a very very good watch, I am an avid Samsung Fan and I was uaing Samsung Sports Active 2 pripor to this watch, I was thinking that I was downgrading but to my suprise I am not missing my samsung a lot, this watch is sturdy very sexy Military style watch with touchscreen it is very light I would have preferredsome weightbut thats me, I haven't tested it any extreme conditions but yeh took it for a hike started with temp of aournd -4 Celsius, as the day progressed temp went up to 5 used the trail walking tool to tarck KM and HR, with GPS I was able to plot full chart of our hike with the Zepp app I should mention GPS and Compass on this watch are amazingly accurate, I use it to track all of my daily workouts, sleep and step there are tons of other options that u can use to track your fitness, Battery life is very good lasts a week, mind u I have have heart rate monitoring on, watch can receive notifications for many apps namely Fb messenger, Whatsapp,Gmail, text but only few line you do receive notifications when some calla u but no name shows up, this watch has no speaker so only vibration notifications vibration is pretty good, has find your phone option, flash light, you cam chnage watch face but via app and watch has to buitlin/saved face, face that are chnaged via app are downloaded on the watch then synced if u want to go back to the pre ious watch face prosess starts again very very annoying as compared to Samsung, what I am missing I can't answer my text or other notifications via typing, voice or handwriting, I can't make and receive phone calls on my watch while connected to the phone. I understand I paid double for that watch so can't really compar, Over all very happy with the watch it is a very good watch for the price I would recommend this watch but please understand this is not a $400 watch but for less than $200 this wacth is giving many many options and has very acurate GPS I am very happy with my purchase
