"its an incredible watch. ... I have never been happier. It is miles ahead of FR 255 in all aspects, workout detection, responsiveness, and functionality. It's amazing for $200. ... the quality, heart rate accuracy, and design are top notch and making quality products, most importantly - at a low cost. ... T-rex 3 is waaay better than $350-$1000 Garmin. I don't think its better than $1300 Fenix 8, but it can compete with it, there are reviews on youtube from credible youtubers comparing these 2. The fact that they are comparing and not finding too much of a gap between $1300 and $200 watches is more than enough to tell you how good T-rex 3 is."

It's amazing for $200. ... this is the main point of buying Amazfit products! ... had my trex 3 for 3 months now, and like it so much more than my garmin epix pro, and, like someone said, even if it burns out, I can buy 2 replacements or more, and still save money over the overpriced garmin stuff"

"Its out-of-box rubber band is quite low quality and gave me insane rashes in a few hours of wearing it."
"With the TRex 3’s default strap on the tightest hole that’s mostly okay but I do use an external HRM during workouts."

"I lost hope in any serious, big updates for Amazfit watches"
"I turned on the Morning Report on my T-Rex, but it doesn't show anything when I wake up."
"Amazfit Zepp app is not better than Garmin Connect, but then again its not really worse, just different in terms of things that do not work, or are buggy. ... Both companies really need to improve their software."

"the readiness doesn't change throughout the day. ... Readiness score needs some tweaks ASAP, it basically doesn't change, no matter the quality of your sleep, like it does say kinda "your sleep quality was okayish, take it easy today, but here is your 87 readiness score" which is absurd to say the least. ... I wish Amazfit added a Body battery kinda feature to look at throughout the day"

"It's huge compared to the instinct. ... Also, it's shape and odd strap made it feel even bigger. ... I changed out the strap with nylon, which helped a bit, but still It's very big. ... the shape made it look comically big."
Aevernum 1.0The sensors suit me. It detects sleep well. It gives advice on recovery. The watch worked in auto mode for about 10 days, 57% remained. I can't compare it with the Pro version, I haven't used the Pro version.
ApprehensivePizza964 1.0The watch so many people have no idea exists, is the Amazfit T-Rex 2 or 3. I prefer the 2 as the size is perfect but the 3 is larger. These watches can do it all and have a battery life on a single charge of 27-30 days. Yes, it tracks your health, phone calls and messages etc. You name it, it can do it. I was dead set on Garmins top watch and stumbled on the Trex at Best buy by accident. Saw it was a couple hundred bucks and can't find anything like it for the price.

Ariquitaun 1.0Amazfit Balance 2 should be about that price. The T-Rex 3 as well for something more sporty. The T-Rex 3 pro is out of that price range, but it's worth the extra. Or Bip 6, or Active 2 round or square, for a cheaper option with the same sensors and 90% of the features and limited local storage. The current gen of Amazfit devices are really very good.
avirup_231 1.0"Honestly there are SO many expensive options out there that do NOTHING, go for mid tier options like these 2 since stuff like this strikes a balance between price and features. 1) [The Amazfit one](https://quancoconline.com/dp-B0DHZDCF6WI) this one’s my top pick if you want REALLY GOOD battery life (27+ days), reliable fitness tracking, proper waterproofing, offline maps, and even AI voice control. Like, it does everything you actually need without turning into a second phone but it does not have google play store or third-party apps so if you’re into installing spotify or messaging apps on your watch, this ain’t it. 2) Galaxy watch6 is sleek, very smooth if you’re on a samsung phone, and probably the best looking out of the bunch. The fitness tracking’s good, and notifications are seamless but battery life isn’t great usually around 1–1.5 days tops, so you’ll need to charge it almost daily."
BeYeCursed100Fold 1.0I love Amazfit. I have the T-Rex and T-Rex 3, the 3 gets about 14-18 days of battery even with GPS on.

ChasingPotatoes17 1.0How small? Mine is 5.9” and I wear a T-Rex 3 and Balance 2. Yes they are large on my wrist but I love a chunky watch. Of the two, Balance 2 is definitely better for less movement on wrist during a workout (which translates to more reliable HRM data).
I tend to wear my watches about 3 finger width behind my wrist bone. With the TRex 3’s default strap on the tightest hole that’s mostly okay but I do use an external HRM during workouts. If I swap in a different strap (similar in style to the Apple sport band with all the holes in it) I can get the device pretty securely in place and have no issues. With the Balance 2 (using the red strap, I haven’t tried the black one) I have zero issues. If either watch were *any* bigger it would be a problem though. They do look massive on my arm, but I like that style. If you’re not sure, the slightly smaller Active 2 might be a safer bet. Feature and sensor wise it’s almost the same. It doesn’t have multi-band GPS, but neither does my Apple Watch 10 and it doesn’t great with GPS accuracy. Sometimes the specs aren’t the whole story.
cryptid_snake88 1.0I have the T-Rex 3 and it's a fantastic watch for navigation. I just done a 3 day hiking and camping trip over a stretch of 40 miles and it never faltered once. It has a great battery also, it does run down after a day if you are using hi detail tracking and have navigation on for most of the day , but if you have a battery pack it charges quickly and doesn't use much charge from the battery pack
earmuffeggplant 1.0The Amazfit T Rex 3 is a steal for the price and features. They also just released a Pro model which has on board mapping and other features typically reserved for expensive garmin models. Battery life is amazing and GPS accuracy has been great for me in Colorado.
FLNguy 1.0I got it for a month now and I am really enjoying it. Just sent some update suggestion on the sports I use to practice (rowing). Even the xiaomi simple bands have moth accurate stats used by rowers, like stroke count, stroke rate and pace in the 500m/min format, not simple speed like if you were riding a bike… it’s an amazing watch, but it also has great room for improvement.
It works, but not with the stats we are used to
No, it does not even have a Stroke count, I sent the suggestion to the Amazfit support, they answered me saying that it’s going to pass to suggestion to the development team. Let’s see if they add these basic features for rowers in an upcoming update
I really don’t get why some watches have SPM, cont and pace as rowers use, others don’t. I had a MiBand7 that had these stuff, and the xiaomi’s and Amazfit OS and app interface are really similar. I still hope they fix that in an upcoming firmware update.
flyingfluffles 1.0I have amazfit T. rex 3 and it’s accurate. Wait for the $200 sale or reach out to customer service to see if they have a coupon.
