    • Excellent smart watch
Style: Smart Watch Only Color: Abyss Black
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. ... show more

    • Nice upgrade
Style: Smart Watch Only Color: Abyss Black
Upgraded from a trex 2. Battery life is phenomenal and I love the default watch face. Does everything I want it too and then some. Much better battery life than my galaxy watch 4 and very close to the trex 2. Can't call or text on it but it does all the notifications well. Was a little weary spending this much but so far so good. ... show more

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. ... show more

    • Wanted to love it
Style: Smart Watch Only Color: Abyss Black
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. ... show more

    • Solid, Solid, Solid! And Indoor Rock Climing!
Style: Smart Watch Only Color: Abyss Black
I bought the T-Rex Ultra after the new Balance was super-disappointing. I wanted a watch that a) works and b) can go from 50-degree cold swim to 105-degree hot tub or into a sauna. T-Rex 2 and Ultra claim they can officially do so. A month in and the T-Rex Ultra has me very happy. A few great surprises: A week after I bought it, they added indoor rock climing function. It's usable and I'm looking forward to it continuing to get better. Also fun, it has water temperature reading available for swimming once you figure out how to set up the screens. My only question on the watch is whether or not the band will hold up to the abuse I'm heaping on the watch. For the price I kind of wish they'd include a spare band just for peace of mind. I'll update when/if it fails. For now, five stars! ... show more

    • A smart watch that lasts 20+ days without charging!
Style: Smart Watch Only Color: Abyss Black
I had a Samsung smartwatch before. I had to charge it every night. I hear the same from my daughters about their Apple watches. When I read that this smartwatch will last 20 days, I didn't believe it. So, I charged it, and then used it 11 days until the battery was down to 50%. Charging it once a week is much more convenient than having to charge it every day, especially when I travel. I don't want to have to carry the charged with me. Now, I don't have to. Also, the charger is really a USB wire with a magnetic connector. I love the watch, how it feels, and how it looks. Very intuitive. The app works well on my phone. ... show more
