    • Upgraded from ultra 2, Outstanding watch and fitness tracker
Color: Tactical Black Size: 48mm
I have the Apple Watch Ultra 2, I hate charging it daily and garmin instinct 2 tactical and this is by far better than both. 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 don’t think I’d use I use a ton working on the farm at night. ... show more

    • Great smartwatch
Color: Tactical Black Size: 48mm
The Amazfit T-Rex 3 Pro is an amazing smartwatch for anyone who loves the outdoors or wants something super durable. The build feels premium with a titanium bezel and sapphire glass, and the bright AMOLED screen looks great even in sunlight. It has offline maps, dual-band GPS, 180+ sports modes, and even a built-in flashlight, which makes it perfect for hiking, running, or traveling. The battery life is incredible — up to 25 days on one charge! It’s a bit big on the wrist, but that’s expected from a rugged outdoor watch. The software isn’t as advanced as Apple or Garmin, but it still works great for fitness and health tracking. Overall, it’s a powerful, tough, and reliable smartwatch that gives you everything you need for adventure. ... show more

    • Love this watch
Color: Tactical Black Size: 48mm
I really love this watch. Still disappointed they have not figured out how to allow phone camera control for Android users, but everything else is fantastic. I'd remove a star for that, but there are so many features that can be used using this watch paired with an android device it's unfair. Like Garmin, Samsung or other smart watches paired with iPhone this watch will not allow you to answer texts directly. You can with android 😁. Not sure what Apple was thinking but they only allow there own watch to do this I use this watch daily for regular usage and athletic tracking and I have been very impressed. I started with the T-Rex 2 then Trex-3 And now the T-Rex 3 pro. I have been impressed from the start. If you're a Garmin user it is hard to break away...they have great features and a robust infrastructure that is hard to separate from. I like. It to tools and once you've cordless started with one battery type it's hard to break away. Well now that I've done it I am happy with this system, from a great app to fantastic hardware this watch rocks. I use this several times a week for cycling Both road and MTB and it performs great. heart rate monitor is spot on with my chest strap and it's easy to use. It pairs flawless with Strava and I have convinced others to make the switch to Amazfit based on quality to cost ratio. There are many smart watch options out there, and as long as Amazfit keeps up the good work I will be using them. Give them a try if on the fence. I think you will be impressed. ... show more

    • If only the GPS could recalculate on the fly…
Wonderful watch. Ton of hardware for the price, huge memory, fast and precise GPS, fast processor, exceptional screen, good heart rate and SPO2 sensor, flash light red and white dimmable, high capacity battery, can work off line, voice commands, very customizable, can play music on Bluetooth, can ask any question with Flow. But… it was designed for fitness. I bought it primarily to act as a safety back up of my iPhone to find my way back for climbing in the 20,000ft range. When temp drop near 32°F and screen is wet it gets difficult to unlock the screen, although I just learnt how to pan and zoom map during workout only by using the buttons. Routing is only available in workout mode which pisses me off every kilometer or so with announcements like average speed bla bla bla that I do not know how to block, but I have to leave the sound on to listen to GPS instructions such as right left back on track or deviate… My main issue is when I deviate to the point that the route is out off the screen, the route recalculate rarely works, but you can always finish workout and create a new route from your location. Also location markers that you previously set do not show on map, plus you cannot give them a name or a number like you do with most GPS and they miss a few icons such as lake summit river parking tent bridge numbers letters... ... show more

    • The Ultimate Adventure Watch – Tough, Reliable, and Packed with Features!
Color: Tactical Black Size: 48mm
I absolutely love the T-Rex 3 Pro! It feels incredibly premium with the titanium bezel and sapphire glass, yet it’s surprisingly comfortable for all-day wear. The AMOLED display is super bright and easy to read, even in direct sunlight. The GPS accuracy blew me away — no signal drops, even when running through wooded trails. Offline maps and route planning are a total game-changer for hiking trips, and the built-in flashlight is such a clever touch. The battery life is phenomenal; I can go on multi-day trips without worrying about charging. With over 180 sport modes, water resistance up to 45m, and detailed training insights, this watch really motivates me to push my limits. Plus, being able to take Bluetooth calls and reply to messages hands-free is super convenient when I’m on the move. Overall, this is hands-down the best smartwatch I’ve ever owned — perfect for anyone who loves adventure and wants reliable performance in any condition. Highly recommend! ... show more

    • 1/3 the price of Garmin and IMO a very good alternative to their flagship line, Fenix
Color: Tactical Black Size: 48mm
I have been a Garmin watch buyer for the last 15 years, from Forerunner, Fenix and my last Garmin watch an Epix 2. After contemplating buying a Garmin Fenix 8 I did some research on current smart watch lines and came accross this watch, and after doing some more research I found out the Fenix 8 and the Trex 3 Pro were being reviewed side by side. I had no idea there was a competitor putting out a product which was similiar in feature set. So I was looking for a durable watch, flashlight a must, mapping a must, a robust watch that would record many of my workouts accurately. To be honest I was skepticle but after about a week of owning this, and I cannot believe I paid just 379 dollars for this watch as Garmin in the 51 mm version was over a 1000 dollars. So for me, not a diehard every metric necessary but more of a middle of the road person who needs good heart rate tracking, accurate mapping and a good application to track all of workouts was a must. This watch is fantastic, and for the money it is a very good buy. I never thought I would be able to abandon Garmin but it appears a new player in this space has entered the arena, offering a very good reason to jump off the Garmin line and that is performance, quality matierals used and 1/3 the price. ... show more

The battery life of this watch is phenomenal, lasting weeks rather than days. It has a built in flashlight (super convenient) with 3 brightness levels and even a red light. The rugged styling of this watch is perfect for outdoor adventures but it also can work for the office by a quick change of the watch face - so many options to choose from.
