Review: Great quality and value - Don’t write many reviews but I’m really impressed with this watch. I previously had an Apple Watch but lost it and didn’t want to pay for an overly expensive watch. After doing a lot of research I opted for the T-Rex 3 which was on offer. Was dubious about the size as I have small wrists and hands and upon opening the well packaged and presented box it did seem big. However, once on my wrist the size didn’t seem to matter anymore. It is remarkably light and very comfortable to wear. The strap has enough notches for any sized wrist and they’re close together so you can get the tightness just right. I have slept with it on and you forget it’s there. The screen is large and vibrant and setup is very simple. There are a vast number of features and they all work very well and nothing appears too complicated. There are plenty of settings to play with and lots of free watch faces to choose from and you can customise what your watch displays. Overall I am hugely impressed with this watch. Has the feel of a more expensive watch, loads of features that work well and a brilliant battery life.
Review: Great watch! Smartwatch equivalent to a G shock! - Great watch!! So I needed a new watch for work as my old Casio G shock died after a few years. As I work as an electrical engineer on the underground power network, I needed a strong watch that was durable in outdoor conditions. I was tempted to buy another Casio G shock but liked the idea of a smart watch but didn’t like the idea of needing to charge it every 1 or 2 days and thought they were a little delicate for what I need it for. After some research I decided to go for the Amazfit T rex 3 and wasn’t disappointed! Pros; Battery life, with daily use battery lasts over 20 days! Sturdy, very well built, don’t feel nervous about using it in extreme conditions, I brought a glass screen protector just for some extra protection Very easy to use and fully of features, very quick and responsive. Cons; Size, it’s not a slim watch, it’s quite chunky which for my I don’t mind as I can live with that trade off for the extra strong built quality and plenty of battery life but just bare in mind it may be a bit too thick to slide under most long sleeves. Connectivity, it’s not laggy at all but there has been a few instances where I’ve missed notifications and the watch has lost connectivity with my phone so I’ve had to open the app and sync it and it starts working again. It’s only happened a few times so not a big deal. Too many features, this can be a pro and con but I find it packed with that many features it can sometimes feel overwhelming and most of the apps and features you’ll hardly use or they don’t work very well. Such as the work out app, it’s great if you’re going for a run but if you’re having a gym workout, the app doesn’t accurately measure reps and most the time you want to have a workout and just get on with it rather then fiddling with your watch the whole time. Overall I’d recommend it, great value for money even though I missed out on the Black Friday deal and paid £253, at £210 on black Friday it’s a no brainer, you’d easily pay a lot more for a garmin equivalent.

### ⭐⭐⭐⭐⭐ A great value useful everyday smartwatch
*by R***N on 1 July 2025*

It's slightly bigger than the old Trex 2 but performs in a similar way. The charger has become a c type and you get a small adapter thats magnetic which sticks to the rear of the watch. Charging is pretty rapid and the battery does last for weeks. I bought mine to monitor my health heart rate etc and in that regard it's pretty useful. The Zepp app links to your watch and will give you a comprehensive feedback on your activities. There is a subscription service should you wish to get ongoing assessments of your health and workout activities. On the wrist it's comfortable and being waterproof and quite tough will still function in and out of water. I found the slightly larger screen useful for reading downloaded maps. It's fairly simple to set up and practically useful on a daily basis. My old watches have become redundant. Would I recommend it yes I would. It's far cheaper than many similar smart watches and every bit as useful. There are literally hundreds of watch faces to choose from free and paid for, the latter being quite cheap too. A very good smart watch.
