Amazfit T-Rex 2

I’ve had the Amazfit T-Rex 2 for nearly 2.5 months and I am extremely pleased with my purchase. During this time, I’ve used this smart watch primarily for fitness tracking, hiking and sleep monitoring. The GPS tracking is extremely accurate. You can set waypoints on a hike and then use the map to backtrack to your original starting point. This is a great feature if you plan to hike off trail. You can upload your own maps, but it is somewhat of a daunting task to do so, which is a con for this watch. The maps generated by this watch are breadcrumb maps, which is fine for me. You can’t read a detailed map very well on a screen of this size. And any adventurer worth their weight is going to have a map of the area they go hiking in anyway. The sleep tracking feature is pretty darn awesome. It tracks my sleep stages very accurately. It also heart rate and respiratory rate as I am sleeping. While the watch itself offers significant insight, the accompanied app offers even more. The fitness tracking feature is pretty much on par with the sleep tracking feature. Just keep in mind these devices only give you relative data as to your heart rate and other vitals. Don’t be a Dilbert and use a smart watch as a medical device, rushing to the ER because your heart rate spiked. The best thing about this watch is the battery life. Holy cow, the battery life. Under heavy use, I can go a couple weeks in between charges. On lighter weeks, I can go as far a 3 weeks before needing to recharge. And the recharging? Well it only takes (I haven’t actually timed it) but maybe an hour or less. The durability appears to be high. I’ve bang this watch into walls, trees, bumped pavement while working underneath a car and the screen is still perfect. Although the glass isn’t indestructible, it is very tough. Other features I’ve used or notifications. I can’t reply to texts or answer calls. But you know what? I’m not trying to be Dick Tracy. If I need to communicate with somebody, I’ll pull out my phone. Free watch faces are plentiful via the companion app or through 3rd party websites such as amazfitwatchfaces. In conclusion, I love this smart watch. The value is insane! The features vs the price should make this a no-brainer for any fitness or outdoor enthusiast.

I've owned this watch for almost a year now. Do I regret it? Absolutely not! This watch has literally changed my life. I'll just start out with the bad. IMO, don't buy this watch for sleep tracking. I think its sleep sensing capability is complete BS. My watch will regularly state that I'm sleeping when I am wide eyed awake at 3 a.m. in the morning. It's so unreliable, that it makes me doubt the entire smart watch industry for sleep tracking. It's a good thing I didn't buy this watch for sleep tracking because I would have been terribly unhappy. So why did I give the watch 5 stars? It's because everything else about the watch has been terrific. And considering it's affordable price, continued free application and watch updates/improvements throughout the year, downloadable apps, GPS tracking, heart rate recording, incredible battery life, etc., I consider it to be the best smartwatch on the market in this price range. The heart rate recording could be more reliable. I have been on the treadmill at times when I know for sure the heart rate sensor on the watch is not recording correctly. It's usually related to dirty (or sweaty) sensor on the back of the watch. But it can also be that I didn't have the watch tight enough or that it was in a strange position on my wrist. Cleaning underneath the watch, moving the watch location on my wrist, or tightening up the band all seem to help get the sensor back on track. It's an annoyance. But I imagine this is going to be the case with most every smartwatch brand and is unrelated to the actual watch itself. The GPS tracking is top notch! Love it. I also love the visualization on my hiking history on the included app. It will color code the trail based on the speed I was traveling when I hiked. It will also record and show my heart rate on a chart all throughout the hiking. The feature that's changed my life is the PAI capability. PAI (Physiological Activity Indicator) is an intuitive algorithm that evaluates multi-dimensional personal physiological data measured by the watch. It converts this data into a easy to understand PAI value or score. The score is based on the HUNT Fitness Study. According to the study, keeping your PAI above 100 will help reduce the death risk of cardiovascular disease, and increase your life expectancy. I have changed my workout to maximize my PAI score. And in doing so have lost 35 lbs of fat in the last year. I've learned a lot about my health, what was causing my lack of results before, and am thankful to the makers of this watch for opening my eyes to it all. Plus, I feel a whole lot better. In summary, for the health conscious, this is a great watch to consider. It's very tough (for outdoor sports and adventures) and long lasting (battery). If you are looking for a watch to help you track your sleep, ehh, better look elsewhere--not sure if sleep tracking is accurate for any watch.

For some perspective, I have been wearing Apple Watches since the day they came out. I also recently decided to try a $700 Garmin smart watch. I can't even say "for the price" (because I don't want people to think that this product is cheaply made, because it is NOT)... my first impressions of the #AmazFit T-Rex 2 are outstanding! I have had it about 18 hours so I will know a lot more in the coming days, but I am so impressed with some of the things they got right that I had to jump on and write a review immediately. So... the strap is incredibly comfortable and has MANY slots with small increments so you can find just the right fit for you. I had struggled with this with so many Apple Watch bands over the years. Also, the watch it incredibly light weight but has enough "bulk" to make it feel like a man's watch and it feels durable. Time will tell on the durability. The screen is incredibly responsive and bright enough to see in bright sunlight. I've only had a limited about of time to check into the different watch faces and have found a few that I personally like. I am hoping you can create your own as I am pretty picky about the info I would like on the watch face. Some of the things AmazFit got right that even a $700 Garmin appeared to be missing: - FIND MY PHONE; the ability to ping your phone when you have misplaced it. Can't tell you how many times I have used this on my Apple Watch. - a quick and easy access to timers; could not figure out how to do this on the Garmin. On the T-Rex 2 it is a simple swipe down and touch the timer icon - SOFTWARE UPDATE (v9.48.1.1) arrived this morning and has some great enhancements. Control center icons are larger, apps menu icons appear larger and cleaner, weather widget has HUGE improvement, and much more. So for my first day with the product, and paying over 70% LESS, the AmazFit T-Rex 2 is an EXCEPTIONAL buy. I'll try to come back after a week or so and product a more detailed review one I have used it more. [NEW UPDATE, 8 days later] So it's been a whole week and I will start with... I WISH I HAD DITCHED MY APPLE WATCH SOONER! I have had the T-Rex 2 on for almost 9 full days and my battery is still at 52%. #AMAZEBALLS!!! I have also begun to learn more about the workout tracking. I added a couple more photos of just part of the workout reports. I selected a Strength Training workout and did both bench press and bicep curls. The T-Rex automatically recognized which exercise I did. I touch one button to stop a set, then in counts the recovery time and then I touch the arrow on the screen to start the next set. When done, I can add the weight or I can modify this later in the app. I don't think Apple is here yet (if they are I never knew that). I am still very much AMAZED with my AmazFit T-Rex 2. Bravo AmazFit.

SECOND UPDATE: Increased stars from 2 to 4. Heart rate works acceptably well IF the watch is very snug against your wrist. I was wearing it a little loose (not floppy but not snuggly either) when I was getting low HR readings. However, by tightening the strap to a snug fit it now appears to be measuring consistent with my other two pulse oximeters. I'm happy with the watch again. UPDATED REVIEW: PASS: • Battery Life – I get six days on a charge. I know this is a long way from their claimed battery life but a) I have everything running (always-on display, heart rate) and b) even at 6 days this is WAY better than most of the competition. • GPS – I walk several different 4 and 5 mile road courses. The GPS tracking is accurate enough for my purposes. This only issue could be that the watch only shows a line for your track/location. You need the Zepp app on your phone for a map overlay. I’ve never used it (the GPS) in an area out of cell phone coverage but would not want to risk getting lost in the deep woods depending on it. • Step Counter – I haven’t actually counted my steps for verification but over my four and five mile walks the counts are reasonably consistent and what I expect. • Watch Faces – Several hundred watch faces from simple to bizarre. Many are free and the prices range from $0.99 to $2.99 so no big deal. FAILS: • Heart Rate Monitor – Like I said I walk and need to keep track of my heart rate and my O2. In addition to the watch I also wear a recording pulse oximeter (supposedly FDA certified for clinical use) and take a $35 finger clip-on oximeter. Whereas the other two pulse oximeters are in reasonable agreement, many times (very often) the watch heart rate monitor is 20 to 40 BPM low over the course of my entire walk. This is more than just a momentary reading that is off due to timing. • Blood Oxygen Sensor – Compared to my two other pulse oximeters which indicate pretty much the same readings, the watch sensor is usually three to four percentage points higher. Also, you MUST remain perfectly still when taking an O2 reading. Not at all useful when exercising. • Barometer – I have had three of these watches (two were exchanged) and all three gave a pressure of 45 hPa lower than the actual. Where I live (Phoenix, AZ) the normal pressure is around 1010 hPa. However, the watch shows 45 hPa lower, or a normal of 965 hPa. You should note that a pressure of 960 hPa is indicative of being in the eye of a category 4 or 5 hurricane! Research has not shown me there is a way to calibrate the watch. • Altimeter – The altimeter is based on the barometric pressure. The altimeter can be calibrated to the correct elevation. However, because it works off pressure and the pressure does fluctuate over the day, my house apparently jumps 30 to 40 feet during the day. • PAI – a) The algorithm for PAI is mostly based on your heart rate. If the watch is not correctly reading your heart rate (see above comment) then your PAI will be way off. 2) According to many web resources your weekly PAI is the sum of your most recent seven daily PAI scores. However, the weekly PAI score indicated by the watch is always significantly higher than the sum of the immediately preceding seven day’s PAI. The are several other Amazon reviews that point this out with pictures. • Weather – There is no choice in the weather service utilized. The service ZEPP uses has limited reporting sites so it is likely your town will not be covered and you will need to reference the nearest city available. Also, there appears to be a significant delay in reporting changes in weather. This is probably more a function of the weather service than the watch but it still provides you with old data. • Calendar – The main issue with the calendar is that “all-day” events entered into my calendar via my phone are always indicated on the watch a day early. A programming glitch for sure that needs to be addressed. • Compass – I don’t use the compass but every time I have “played” with it I have to first go through an aggravating calibration routine. Not something I would trust in the woods. Who Knows: • Sleep monitor – Sleep monitors on any watch are extremely subjective and questionable. • Calories burned – Again, subjective based on an algorithm. CONCLUSION: An expensive piece of hardware to tell you the time (which it gets from your phone) and to count your steps. Not worth it in my opinion. ORIGINAL REVIEWL Great battery life (7 days) even with features (heart rate, O2, always-on feature) activated. However, barometer is WAY off and that and the related altimeter are a waste of time. GPS tracking is fine for tracking my 4-mile residential area walks. Love the PAI workout feature but although the daily PAI makes sense, the math for rolling 7-day total is off. There are new watch faces available daily. I'll keep it.

I used to own Galaxy Watches and loved them, but since they stopped working with iPhones, I switched to the Amazfit T-Rex 2, and I couldn’t be happier. This watch is loaded with features that make it a standout for anyone who works outdoors, trains regularly, or loves hiking. The auto workout detection makes it effortless to track activity, and the advanced health monitoring (sleep, heart rate, blood oxygen, and stress) provides accurate insights. The dual-band GPS is extremely precise, which is a huge benefit for hiking trails, running routes, or navigating job sites. Add to that its military-grade durability, and it’s built to handle heat, dust, sweat, and rough conditions without missing a beat. The battery life is phenomenal — almost a month on a single charge, even with all features enabled. That means no worrying about charging it daily, whether you’re on a long hike, working long shifts outdoors, or training hard. The health reports have been an unexpected bonus, I’ve been able to share them with my doctor, and the data actually helped identify and address health issues. The only drawback is the band and limited accessory options, though the original one has lasted me a year. I also didn’t purchase the AI software due to the price, but even without it, this watch already feels feature-packed and complete. Pros for outdoor workers, athletes, and hikers: • Rugged durability for tough environments • Accurate GPS for trails, routes, and job sites • Nearly 30-day battery life — perfect for extended use • Automatic workout detection and detailed tracking • Comprehensive health and sleep monitoring with reports you can share with a doctor Overall, the Amazfit T-Rex 2 is more than just a smartwatch — it’s a reliable tool for fitness, health, and outdoor life. I can’t go a day without it, and for me, it’s an easy 5 stars.

The battery, speed, features, durability, clarity, and accuracy are outstanding. You cannot beat the price and quality of this watch. The battery is as good as they say it is. If you use it constantly through the day for various things it will not last the full two weeks but it is still much better than any smart watch I’ve owned. I’m on day 3 now and at 74% battery using it a lot. I’ve fiddled with it through the days using it as often as I can. The OS is smooth and runs very snappy. Running a timer and the stopwatch while using a compass? No problem! Some of the free watch faces have the ability to allow you to go directly to various apps on the device or tells you what is running or if Bluetooth is being actively used. Too many features to go through in a review here but it has plenty of information. There are some watch faces that provide you with tons of useful information. Metrics, date, weather, moon phases, barometric pressure, rain warning, sun rise/set, alarms, screen lock, humidity, etc.. it’s a lot. It’s durability seems to be really good. It is plastic so it’s very light but still feels very solid. I haven’t felt like it’s going to break if I bang it on something (which I have and it is unscathed). The band I think is great but I did see where some people have broken there’s. No worries though because there are replacement bands through AmazFit and aftermarket; I bought an elastic breathable band and replacement was easy. UNSCREW THE LEFT SIDE (side with up and down buttons) ONLY! Otherwise you’ll strip the tool. It requires a special tool so make sure the band you order has the tool to remove the screws. Overall the quality is outstanding. Screen clarity, resolution, and readability in the sun is amazing. It will adjust screen brightness automatically depending on the lighting around you. Colors are vivid. And finally accuracy of the metrics for health and sleep seem reliable. I’m not a health nut so I don’t need it to be 100%. That said it tracks on par with Fitbit and various other watches I’ve used. The graphs and layout of information is very in depth yet easy to read. Sleep tracking seems to be very accurate and comes with an optional subscription to allow ai enhanced ambient sounds customized to your sleep pattern. It learns what helps you sleep better and shuts off at the appropriate time and uses a smart alarm the wake you up slowly within 30 minutes of your set alarm. So not to wake you abruptly. This is a game changer for the price and I’m grateful I chose to try out this watch. As long as Amazfit keeps doing what they’re doing, they have me as a customer for life. 5/5 stars!

4 years of use, battery was holding for a whole month, untill now, very fair for this amount of period. Great value for your money. Getting an Ultra 2 to replace it.

Unfortunately, some of the biggest features that T-Rex 2 has advertised over its previous models is the custom training plans and the ability to import .gpx files for navigating routes are not available until late July. Which led me to return the item as so many tech companies over sell and under deliver on their products. For what did work, the function was surprisingly good; very good in-fact! The T-REX 2 has responsive buttons to compliment an equally responsive touch screen coupled with a fluid well designed OS. A stand out feature was the accuracy of the sleep tracking which seemed to surpass my fitbit charge 5. Aesthetically, I liked the rugged look of the watch with one exception on the bottom lug bar is an embossed white lettering "T-REX" which looks cheap and the watch band looks to be proprietary. I was unable to remove the band to confirms as the band is held by triangle screw heads on either side (I didn't have a driver to remove them). Once the late July update hits, I would have no reservation recommending this watch based upon my experience and it's low price point. The functions of this watch sit somewhere between a Garmin Instinct 2 and a Fenix 7. The big deviation from a Fenix 7 is the T-REX 2 will only have breadcrumb routes to follow vs a full fledge map. Construction of this watch seems to be very well built, but I still believe long term that a Garmin product will outlast an Amazfit product. Finally, there is the concern of privacy as I believe Amazfit is a Chinese company that is also headquartered in China. Since I do not work at a sensitive location I really could care less who is monitoring my watch (time will tell if that is naive of me). Considering the price-point of these Amazfit devices it leads me to consider if a revenue model exist to profit from a users' data; then again maybe Garmin just charges a significant premium for their devices. Regardless, my choice is spending more for a Garmin as it delivers what is advertised from delivery and Garmin has a track record of lasting for many many years.

Este reloj Amazfit no tiene absolutamente nada que pedirle a un GARMIN!!, que son para mi gusto muy buenos pero a la vez demasiado caros!. Las mediciones son muy precisas, lo uso cada día para correr y es increíble!!, me gusta mucho su calidad de construcción, la cantidad de funciones que tiene, la enorme cantidad de carátulas que tiene para escoger y la facilidad para usarse!!. También me gusta muchísimo la duración de la batería, que aunque no me llega a los 24 días, si me ha durado sin problema a los 15. Lo único que le faltaría para que fuera perfecto es que tuviera carga solar. También me agrada mucho es que puede recibir todas las notificaciones que tú quieras de cualquier aplicación, cada vez que recibe notificaciones el teléfono, en la app del reloj van apareciendo las aplicaciones para que tú elijas cuáles quieres recibir. Una de las cosas que no me gustó mucho fue la correa, la siento muy delgada, pero aún así es muy cómoda, en resumen estoy muy contento con el reloj!, no le pide nada a un GARMIN, y siento que hasta es mucho mejor!!

Honestly, what do you want from a Sporty Smart watch? This looks very decent, gives me the right data about my workouts, sleep patterns, heart rate, stress levels & even has a built in GPS. Full Touchscreen interface, nice vibration notifications, Loads of watch faces to customize, and most importantly for me, a amazingly LONG LONG standby time (seriously, I've used it for a week and it still tells me I got 50% or more battery life) love it... An amazing interface via the ZEPP app and finally, the Price... C'mon for all you're getting, and you think it's expensive, you obviously didn't do your research on the competition at all...Its a solid buy and for all you're getting worth every penny (even if you've already saved by getting this watch)! Just go for it!

I bought this watch last year around Oct and wasn't too sure as to how it would perform. But after using it for 8 months I can confidently say that for the money you pay , this watch performs pretty well and it would definitely be on par with the more reputable watch brands out there and perform as well penny for penny if not better. I use for my road and trail running once or twice in a week. The GPS is spot on, thought I should mention it does take a wee bit of time to search for the GPS, sometimes it's faster. But that's a small issue. Once it's on , it's good to go. Whether you are hiking or running, the watch will give you pretty accurate metrics. Honestly I have not fact checked for every sec or heartbeat but whatever I read at the end of the activity or workout, I feel it's pretty accurate. Like they say, you cannot substitute it for a medical device. For a lay person like me I feel this watch is fantastic. It's got all the features which one would find in today's best smart watches. I took to Bharat this year in Mar / April and May and worked like a charm. Finding the GPS was no issues. Used it for running and walking, no issues. Also used it for my river rafting trip at rishikesh for 17kms down the Ganges, dived into the river while rafting, no issues. I don't even remember, like cleaning the watch afterwards. I took it for the Tungnath trek upto 12000 ft, no issues. Next year I'm planning everest base camp trek and I'm sure this watch will pass with flying colors. What I also like, since I do high altitude trekking, is blood oxygen that it shows. Again, I know it's not supposed to be used as a medical device, but atleast you get an idea, so yeah overall very happy with the purchase and the watch. Did I forget to mention that I wear it to work everyday ? The battery life is also pretty amazing. Depends on what features you use but if you keep it simple and basic then the battery really lasts long.

BUY IT !! ( save you some reading) Still unsure... read away. I have had some other AMOLED watches before taking a chance on this watch. So I get the hesitation. BUT I will say, the price point to the quality of the watch do not line up at all. This is a very good watch. It is worth it !!!!!! Sure who am I right... but I will explain my high rating based on my life. I am a journeyman plumber and this makes a nice work watch. Controls Spotify easily, volume +/- and skip songs forwards and backwards. Message notifications / phone calls show up with a great vibration. Even using a SDS plus I can feel the watch vibrate. My last two smart watches I couldn't. Using a SDS Max - not so much but that is expected. I do not use any of the GPS or heart/health stuff. I do glance at the step counter at times. I know what I typically do daily and seems fairly accurate as well. I am over 50 and with this age comes seeing/reading small print an issue. My favorite thing about this watch is the screen is large / very bright which makes working/driving very easy to see what the message is / who is calling. Even in direct sunlight, while driving / working outside, still read the screen with ease. Few times I did work outside in the cold Winnipeg winters, watch worked fine. Battery life is impressive. Not sure about there "days" they post it can last. This watch can easily go 1 week using the watch often with the screen bright. I tend to get a lot of calls and messages daily and I only charge it Sunday mornings. One of the first things you need to get is the AmazFaces app. LOTS of free watch faces to check out. You will have to watch some ad's on the app to get the free faces but so worth it. Posted some pictures of some of my favorites. TIP: Issues loading a face. Reboot the watch. After a few in a row, tends to fail. Unsure if its a phone / app or watch issue. Not a real concern as a reboot of the watch is quick and easy. Tip: ALL AMOLED screens have issues with burn in on the screen. Just like your parents/grandparents watching the weather channel and when the TV was on a different station you can see where the time / temp /city info on the screen. This screen are bright but it has a cost to it. So a trick I figured out early on ( after I ruined my first Garmin Venu) was to change the face display often. I tend to cycle threw about 8-12 watch faces. This will help reduce the "burn in" effect. I only have 3 CONs for this watch: 1) is the strap. I love the dual clasps ( rings that hold the extra in place). Just the remainder of the strap sticks out to far past the last selection on the band. It tends to get caught on the steering wheel when palming a turn hard / parallel parking. ( see picture) 2) Amazfit DO NOT SELL extra bands. Which I do not get it... I reached out to them and all I got back was " check out amazon.com/.ca" there are lots of aftermarket straps. So I went down that rabbit hole and all these aftermarket ones do not have the dual rings to hold the extra strap, which to me being physical all day while work was a HUGE importance to me. 3) This one is kinda petty but... When you clear your notifications on your phone. Watch takes a long time to clear them, to the point I had to manually delete the notifications. Yet at times it does it instantly. so... ya My Garmins and Fossil instantly cleared them instantly. Ya ya I know petty. Just letting others know incase they run into the same expectations Buy this watch ! Price point is spot on !!! Watch is very good!! Winnipeg MB April 6th 2024 is when I made this. Hope I helped !!!!!!!

I did some reviews and research before buying. I am very satisfied, it has a very intuitive sleep function, built in GPS and compass, fitness monitoring and I get a solid 7 day battery life even though I leave the blue tooth on 24/7. Rugged construction. The only fault in the unit is you cannot turn off the blue tooth from the watch would have to turn off the watch to reset, this is a software issue that can be resolved.
