T-Rex Ultra 2. Why the HR accuracy while running is so broken?
If you watch the TQS review of the Fenix 8, you will see similar problems to the ones that the T-Rex Ultra 2 shows. Heavier watches simply have more misses than lighter ones. You can observe that behaviour by comparing Forerunner 970 and Fenix 8 (again, watch the TQS reviews of those devices) or els

Has anyone else left Garmin for Amazfit recently? Just made the switch and genuinely impressed
amazfit 厲害的是它們的高階表的價格是garmin中階甚至是低階表的規格, 這就是amazfit c/p好的地方, 但Garmin厲害的地方是GPS追蹤能力跟inReach是amazfit沒有的, 我同時有Fenix 8 51mm amoled 跟T-rex Ultra 2 這兩品牌手錶, 我不會放棄其中一個, 我認為這兩隻都非常棒, 各有缺點, 另外也有網友PO過amazfit的GPS精準能力不足, 不如Garmin, 那是因為amazfit少了Garmin精準定位的相關軟硬體(畢竟Garmin最厲害的就是GPS定位導航在軍事/民用方面), 我自己有比對過, F851與TU2在高度計上

A watch for the helio strap
I would get the Active 3 Premium myself with these requirements. Really nice device. No dual-band GNSS, but on the whole that is not really necessary if the GNSS implementation on the whole is good, which it absolutely is on current Amazfit watches. Using the Helio Strap as my primary HR monitor in

Amazfit Trex Ultra 2: Comprehensive HR Re-Test
Aunque el T-Rex Ultra 2 pueda llevar los mismos algoritmos, el mismo sensor, y las mismas actualizaciones de firmware que otros Amazfit de gama alta, diría que su peso y dimensiones a buen seguro le penalizan para según que deportes. Los resultados con uno de los nuevos Cheetah 2 o los nuevos Balanc

Helio Strap Accuracy - Very BORING, Fitbit Air is far more interesting
I didn't expect that about the Fitbit Air, that's terrible performance. u/the5krunner thank you so much for this post and all the time/work you are taking for the Amazfit reviews. --- BTW, can I ask for an Amazfit altimeters review? I'm missing a review comparing Amazfit watches and other brands. I

Amazfit Balance 2 Bricked after 15 Dives (Pressure Sensor Failure) – My review & experience
Read the Notes of both products. Watches and certifications are not only the 10ATM thing. If you read the Notes you'll notice that It is certified for higher and lower temperatures, while the Balance 2 not. That means that is not only that does look 'more rugged' but encapsulation is very likely mor

T-Rex Ultra 2 battery life significantly worse than T-Rex 3 — same settings
Honestly, I got the Ultra 2 mainly because I find it more beautiful than the T-Rex 3 — the silver case just looks more premium to me. But I have to be transparent: in practice, it's been a disappointment in almost every functional aspect. The battery, despite being theoretically larger, doesn't actu

Amazfit Cheetah 2 Pro vs Garmin Forerunner 970, Urban GPS test
The Forerunner 955 altimeter is very bad, while the Fenix series altimeter is very good. The reason is that in the Forerunner series the altimeter is under the case and at the end, it gets dirty with sweat/dead skin cells. The temperature of the body also affects to the accuracy. There are many repo
