Review: Great watch! Terrible band! - 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!

## Questions & Answers

**Q: So; first on the market was the amazfit pro; then cames out the amazfit pro-2 and now the newest is the amazfit pro ultra?**
A: The very first model for the T-Rex line is the T-Rex and in the order after are T-Rex Pro, T-Rex 2, and T-Rex Ultra. 

Michael | Amazfit Support

**Q: Any reviews about the pro ultra? i only found from the pro and the pro-2. the ultra price is twice of the pro 2 so i want to read opinions from users**
A: I like it better than my 300 Dollar watch but it has no sound, the watch has a listen to music option but you can't.

**Q: Que diferencia hay , entre el t rex pro 2 y este reloj ??**
A: Eso no lo sé pero son los mismos en la descripción del reloj está está ha salido muy bueno lo mejor es la duración de la batería

**Q: Why is the t-rex ultra so expensive? the additional build quality and minor features simply don't justify the high expense**
A: It's a bit more rugged and capable of tougher use. The price point is really up to you.  I went with the T-Rex 2 to get to a price point I thought was more feasible.

### ⭐⭐⭐⭐⭐ It's the best..for me
*by T***D on March 1, 2024*

This watch is fantastic! This is my 4th smartwatch. I've had the Samsung, 2 different Fitbits, and the apple watch. I am an iphone user. Nothing can compare to the apple watch paired with the iphone, it's seamless and the display is just beautiful. All that said I hate the way the apple watch looks. It looks like it was designed by girls for girls. Nothing against girls but I want a smartwatch that looks like a watch. I liked the look of the Samsung but just like the apple watch the battery life killed all the positives. This Amazfit T-Rex Ultra is beautiful, a man's watch, and I get 5 days of battery life normally. I know that's not the 20 days advertised but I like the always on display plus I wear it 24 hours a day everyday. The incredible things include nice display and many awesome watch faces. App is also pretty awesome. The workout and sleep feature details are also great, One huge thing is how fast it charges. I can pop it on the charger at 5% and it will be fully charged in 45 min and if needed you can charge it for like 10 min and get another day out of it. Bravo amazfit! Yeah you can't respond to text or answer a call on it which i'll admit are convenient features but you do see text and notifications and it lets you see the incoming call and reject it. To me the trade offs are worth it cause it's beautiful and pretty great all around. If you like your apple watch or your a girl then keep your apple watch because this is not really better...or is it?
