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!

I had every single T-Rex version but this one is definitely top notch. New software, improved interface, 20-day battery life on a regular use, steel case are definitely worth the money. I like that you can change the bands on this ultra model so I fitted mine with carbon fiber Luminox band. Totally changes appearance of the watch without adding any weight. I took it on 10 day vacation to Mexico and swimming in the ocean was no problem with this watch. Quite accurate heart rate and step counter as well as O2 levels. Didn't try blood sugar or blood pressure monitor but that's not what I bought it for in the first place. Two small nuisances... On the 1st time getting GPS lock can take some time but it works fine afterwards, second...I still do not understand why the Amazfit didn't implement option to increase font size on the watch on the 4th iteration of Trex. Screen resolution and AMOLED display are certainly excellent and I don't see why they can't or won't do it Bottom line I would recommend this watch to anyone looking for rugged SmartWatch with long battery life, extensive amount of watch faces and customization, external applications and so on. It is not on pair with Garmin watches for professional athletes but for every day use for fraction of the cost definitely highly recommended.

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.
