Amazfit T-Rex Ultra Tactical Smart Watch for Men 47mm, Military-Grade Sports Watch, Dual-Band GPS, 20-Day Battery, Android & iPhone, Black

Ok, everybody has terrible bands these days, so I am deducting no points. The band in the picture is the Hēmsut leather band you can get separately. I am converting from a Fitbit Versa 4 that has served me well, but I did it a battery injury while in a hospital bed FOR 2 MONTHS and it now needs to be charged daily to log my heart rhythm and SpO2 levels, which is too easy to forget. I need the hourly logs to have with me for cardiologist visits as we monitor my artificial heart valve, 20 years old and still running! The T-Rex Ultra is OVERKILL for what I want, but I was after the battery life and water resistance (I’ve murdered a couple watches in a swimming pool, finding that “10m water resistance” doesn’t compete with dive ratings) which it covers across the board. I charged it when it arrived, then had to run through 3 firmware upgrades to get to the current OS, Zepp OS 4. That was 3 days ago. The watch, despite having hourly testing on, WiFi active, and live Accuweather running, still has 76% left on the battery. That’s awesome! A lot of the workout tools I have only poked at, not put to use fully, but I am recovering from muscle atrophy following my hospitalization. When the weather warms up, the pup and I will be putting it to use and if there are issues, I’ll come back and add it. Overall, considering I was looking at a Garmin watch for 3 times the cost, I’ve compared capabilities between it (my close friend owns it) and the Amazfit holds a dead even rating. That says a lot! Thus far, I’ve banged the glass into my guitar and the inside of my server with absolutely no scratching. The steel frame helps. Overall, for health needs, I can log everything in Apple Health on my iPhone, export to a spreadsheet in Google Docs, and have detailed info for my docs when I have appointments. I couldn’t ask for better usability. 100% cat compatible!

First of all, I am a previous iWatch person. I have had three, my last being the iWatch ultra. I purchased iWatches for the features, heart rate, exercise, etc. I was never happy with the square shape, but I used it to monitor my activities, sleep, heart, oxygen. I was never happy with the battery life, I was having to charge every day. Then I purchased this watch after doing some research. It does everything the iWatch does, but in my opinion better. It looks great and it is very dependable and rugged. The battery life is great. For example, I charged my watch four days ago and I am at 75% now. I would highly recommend this watch.

My last smart watch could go for about a day and a half on a battery charge when it was new with something like 6-7 hours to recharge. After a beautiful relationship that lasted 7 years, I finally had to say goodbye to it because it was down to about 6-7 hours per charge. I've had the T-Rex for two months now and I've only had to charge it twice - and one of those was just to top it off the day I received it. And it recharges in about 45 minutes. Holy cow. I mean, they claim it but I didn't believe it. Then we get to its list of features. I don't typically wear a watch while sleeping, but I've worn this one a few times just to see what it has to report. What it's able to figure out from just a few sensors on the bottom of the watch is pretty impressive. I haven't used its GPS capability yet, but have worn it during workouts and it's impressive there, too. I had never heard of this brand previously so I had a little bit of trepidation, especially with this watch's sticker price, but I have to say that I'm quite happy with the purchase. DO keep in mind that it's a heavy watch, which I knew wouldn't be an issue for me. I also paired it with a fairly heavy metal band, so it's 5 oz/ 140 grams on my wrist.

I had this watch for a month but the things it didn’t do or did differently than my Apple Watch was more than I could overcome. I really wanted to love this watch. It was built like a tank, looked awesome, and had a great app. The things I didn’t like were lack of being able to respond to text and calls via the watch. Heart rate monitor seemed to be off after upgrade. Not compatible with treadmill connectivity. Battery life was incredible, band options were limited. I have returned it and will stick with my Apple Watch for now. I miss it already.

This watch is phenomenal in getting you into shape. They're is a huge program of information for the tech junkie. Also in tracking food, heart rate, and sleep.... I never knew a product could help me so much. The battery is so good you forget to bother with charging. The display and features keep you on track and as an ex trainer, I would recommend this for all clients. Great job Amazon. You knocked this out of the park. I immediately (7days) bought my wife one to help her. Corey

Un reloj muy robusto, una pila de muchísima duración, mediciones muy precisas y en general una experiencia de uso excepcional. Muy recomendado.

Compre este smartwatch y al quererlo configurar me pide contraseña, es normal o será que no es nuevo ? y si fuera normal cual es la contraseña
