Amazfit Active 3 Premium smartwatch is official

Probably the most unneccesary release I've seen from Amazfit, alognside the T-Rex Ultra 2. They haven't been able to keep up with the Helio Strap demand, still unable to sell a single replacement band for the Helio Strap, the calories algorithm is still super high, sports like swimming are still lac

Amazfit for serious sports training

Amazfit hardware is fantastic. For reference, in the last couple of years I’ve owned and trained with the following (I’m not rich or crazy, but I got really used to having a bunch of devices during grad school when my research called for it).

Switching from Garmin

Long time Garmin user here, Fenix 8 now. I got an T-Rex 3 pro a few weeks ago to test it. I was very surprised by how good it was. I made a list of my own (subjective) pros and cons. I don't list things that are pretty similar, just the differences that mattered to me: Pros amazfit: No forced sleep

Is anyone satisfied with the T-rex 3 pro?

I have used the T-Rex 3 Pro for about two weeks now, in conjunction with my Helio Strap that I've been wearing for about 4 weeks. And I'd call myself very satisfied so far. I have to mention that these are my first fitness wearables, so I cannot really compare. As a tech savvy and relatively sporty

Returning the T-Rex 3 Pro . Same issues as ever

What do you mean "euro increase"? The watch costs 400 eur total. ESim - I am glad T-rex 3 pro does not have, it would just increase price and many people so not need it, including me. HR on my T rex 3 works great, even more accurately than on Fenix 7. T rex 3 pro should be the same. Moreover, Garmin

Thinking about pulling the trigger.

Hi, I'm mainly a runner and occasional cyclist. I've owned many Garmins (310xt, 910xt, 645 and 745) plus a Suunto Ambit 2 and a Suunto trainer.. Last November I purchased a T Rex 3 (non-pro) on special offer for under $200 here in Mexico. I can tell you that this watch is the best watch I've ever ow

Just need a watch that does the job and has decent enough monitoring with things like HR and steps.

I used to think exactly the same: I just need a watch. Something that tells the time, maybe counts a few steps, maybe syncs with my phone if it’s feeling generous. That was the whole plan. A simple man, simple needs. Then, somehow, it turned out the watch should also be waterproof. Then it should tr

Amazfit Trex Ultra 2 Review

I totally agree that Amazfit's algorythms do not filter noise as fine as Garmin watches. In the T-Rex 3 Pro I have cadence lock and in the Ultra 2 I'm seeing the HR accuracy is not as good as it should

I love the T-Rex 3 Pro SO MUCH!!

My T-rex 3 pro is much more accurate in sleep tracking than Garmin Fenix 7. Inaccurate sleep tracking in Garmin makes its body battery and recovery metrics inaccurate as well. Amazfit imrpvoed significantly its sleep tracking by software updates, it is now much better than before. That said, I do no
