Amazing smart watch at a great price!
Color: Black Size: 44mm
Review Image by Garrett
Ill start by saying this is my first wearable in almost 10 years and I dont have alot of experience with other wearables or smart watches. That being said, I tend to research things for weeks before I buy. After hours of YouTube reviews and comparisons, many Grok queries, and what feels like endless google searches i finally pulled the trigger and bought this watch. All I can say is wow... this watch literally does everything I wanted it to plus alot more! My primary wants in a watch were telling time (obviously), sleep tracking, heart rate/ health monitoring, and being durable (i work in construction). This thing accomplishes all of that easily. It also has other features that I didnt know I needed but cant see myself going without now, most notably the built in flashlight. Its bright and incredibly handy. Notifications are easy to read and respond to while phone calls are clear for both parties. The battery life is great even though im only getting about a week out of a full charge. Thats by my own choice though because i turned the heart rate check rate up. Also super impressed with how user-friendly both the watch and the accompanying phone app are. The phone app gives you a more in depth look at all the health metrics that your watch cant give you due to screen size limiting. Once I decided I wanted to go with the T-Rex 3 pro I had a hard time deciding between the 44mm and 48mm options. I ended up going with the 44mm because I didnt feel like my wrist size was suitable for the bigger watch and im happy with my choice. Ill post a picture of the watch on my wrist which is roughly 7inch diameter. Honestly I could write more great things to say about this watch but im not going to go into all the tiny details. If your in the market for a rugged/durable smart watch I definitely recommend this one. Its basically a Garmin finix 8 at a fraction of the price. ... show more

This watch rocks
Color: Tactical Black Size: 48mm
Review Image by kgb
Battery life is insane. You can actually use all the features on long hikes without having to worry about the battery at all. Screen is nice and bright, easy to read in direct sun. Auto adjust for ambient light. Titanium and sapphire crystal are holding up very well after rough use. Very smooth UI. GPS tracking is dead on through urban or forests. Offline maps are easy to use and work perfectly once downloaded into watch from app. Quick GPS lock. Very easy to see and set waypoints, or backtrack your trail on the map from the watch itself. Microphone and speaker is a game changer for spoken directions while hiking, voice calls, and using the integrated AI that runs chat GPT. Flashlight is beyond useful. Vibration alerts are nice and strong. Charges quickly. Tons of watch faces and apps to download with plenty of memory for everything you want. All sensors seem to work within tolerances along with the fitness tracking and goals. This thing beats the snot out of my Garmin. ... show more

Great purchase, long battery, durable, stylish
Color: Tactical Black Size: 48mm
I got this just over a week ago, switched over from a Samsung Galaxy 5active watch, I would tend to charge my Samsung nightly as it would be at usually 65% by the end of the night after wearing from morning, I got this watch, charged it to 100% and put it on at 11:30pm a week ago, and it's now on it's 8th day at only at 37% granted I have a pretty active watch face set that has an active radar style hand that moves every second and makes a circuit every 60 seconds, it'd probably be at a higher battery percentage, but anyway, I use it for my text notifications, call notifications and general phone application notifications, timer for lunch break, morning alarms, sleep tracking, gonna switch back to a static watch face and see how the battery fares with that instead of an animated watch face, oh I also have it set to raise wrist to wake screen as well, but I'm very much pleased with this purchase, I've put an aftermarket watchband on it and the flashlight comes in handy when I'm at work in the back warehouse at stores merchandising in the stock shelves where light is limited. Oh I have an Samsung Galaxy S25 Ultra phone, I heard text reply on the watch isn't compatible with IOS. ... show more

Upgraded from ultra 2, Outstanding watch and fitness tracker

I had the Apple Watch Ultra 2, I hate charging it daily, T-Rex 3 pro and a garmin instinct 2 tactical and this is by far better than three. I do not even wear the Garmin anymore I like this one so much. Great features and quality of a high end tracker. The apps work great and it’s easy to use. I love the gestures of swiping left up down etc it’s a lot more intuitive than my ultra 2. I love it so much I got rid of my Apple Watch Ultra 2 and this is my main watch now. I like the bigger size and the weight is great. It looks nice and am happy I chose this over the garmin instinct 3. All the features of the instinct an ultra with great battery life it’s an amazing value. I had to edit and add how much I LOVE the flashlight feature, the one thing I didn’t think I’d use I use a ton working on the farm at night. The OS is so smooth and the app data is great no subscription required. Update: Watch band and charger are trash and had to get a few new watch bands. And an additional charger 2 for $9. I signed up for Zepp pro $45 a year and you get 2 free watch bands and pretty much a ton of free watch faces that normally cost. Plus ai access. I train Hyrox and a lot with kettle bells, slam balls etc and this thing works like a dream. I have it 4 stars cause of the price end the watch band is very stiff and cheap. Attached is a photo of one of the free watch bands I got from amazfit. Also deducted the star the charger prongs leave a dent on the contact points on the watch so you’ll end up buying a new charger because it’ll stop charging due to zero contact ... show more

This is the best watch I've had and I've had a lot. I've had the Samsung Galaxy watch 7 the Google pixel watch 3 The ticwatch Pro the Garmin instinct 2 solar and the suunto race and this one has just as long battery life as my Garmin instinct. 2. With a way better screen goes up to 3,000 nits has offline maps, a built-in flashlight which the Garmin also had and I really liked. It is extremely fast, responsive screen, very visible weather, low light in direct sunlight. I did like my pixel watch 3 but what I didn't like was charging it every other day. But this one has a larger and brighter and better screen. You can receive and reply to text. You can receive and talk to phone calls. It's a great watch. I am now in a Mace fit fan and I'm also buying the amaze fit Helio strap for the days I want to wear my traditional watch ... show more

awesome
Color: Tactical Black Size: 48mm
This watch it so cool, has so so many more features than my Garmin and cost pretty much the same price. Top Notch build quality, rugged, nice and bright, everything's adjustable, easy menu to navigate. Love the touch sensitive selectable areas on the screen, that's just a game changer. Tons of biometrics tons of watch faces and apps. I'm hoping the next model is a little Slimmer but no big deal the battery lasts weeks with everything almost everything running. My only complaint is that the music downloading to the device was extremely difficult, never really got it to work quite well, only got a few tracks loaded and gave up. This part can seriously use some work. My Garmin was pretty cool in this area cuz you could plug it into your computer and look up the songs on the device almost like a ext. drive which this one does not allow you to do . but not a huge deal cuz I don't use that much. ... show more

So far everything works great as described
Color: Tactical Black Size: 48mm
The watch is overall pretty great, comfortable and big enough so I can choose a lot of data to view or just a large clock display. It took a bit to figure out how to download music but this is how...To download music to your watch, you have to turn off your cellular signal and the VPN (if using one). Make sure you're Wi-Fi is on 2.4 GHz on the watch and then your phone. The download has to be an MP3 or flac file that is already stored/saved on your phone. It will not work for streaming services that I know of. Use the music icon on the device app. Battery life is great, I've only charged the phone to full capacity once when I received it and it is at 48%. I use the flashlight, fitness tracking and music... Awesome that I can track all my health and sleep. A little something to help keep me accountable. Very nice. ... show more
