Amazfit T-Rex 2 Rugged Smart Watch 47mm, Military Certified, Dual-Band GPS, 24-Day Battery Life, Ultra-Low Temperature Operation, AI Fitness Coach, 150+ Sports Modes, for Android iPhone(Black)

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.

First of all, I love the ranger green color, it is definitely a favorite color of mine. This watch has performed so so well. I enjoy being able to track my steps and sleep. I am surprised how accurate it was with my sleep time and when I had to get up during the night for when my son or puppy woke up. This watch is surprisingly durable. I have smacked it on the corners of countertops, door frames, etc. and there is no scratch on it!!! I am thoroughly impressed with it. I did take it into the shower which had no issues, but the problem is moisture gets stuck in the crevices of the band so it's hard to thoroughly dry. I would just take it off before you get in. Now the battery life, it is amazing!!!! I love having a watch that I don't need to worry about the battery life. I typically get 20 days (5% a day) so when the low battery notification comes on at 10% I have 2 days to charge it. The watch also charges up to full in like 2 hours. This watch is perfect for me. It looks awesome. Works great absolutely no issues. Battery life is phenomenal. Great features on the watch. I would highly highly recommend purchasing this watch if you are looking for something like this.

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!

Good price good quality Battery life is very long App is easy to use Nice design

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.
