I am using Galaxy Watch 7 and Amazfit Active 3. Amazfit is closer to my professional medical devices from work. Edit: and topo maps are better than any app on Wear Os
Might as well go with the active 3 premium.
You're not the first nor will you be the last making that amazon association. The max and the 3 premium aren't identical though, they have a lot of overlap but the 3 premium has some unique features like full button navigation and certain running metrics as well as on watch gps routing and higher grade materials. But it has a smaller display and battery.
I agree, I'm disappointed. I wear my Active 2 when I want a smaller stylish slim look than my T-Rex 3 Pro 44mm. And in those situations, I don't really need all the buttons. The Active 3 looks like less stylish and is larger and thicker. They need to focus better on who the audience is for each model.
In digging through the specs online, I get the impression the heart rate monitor can still only do every minute rather than continuous. Not a critical feature, but I like being able to look at my watch outside of workouts and see my heart rate.
every watch with a more than decent GPS and HR sensors can be ok for you. An Amazfit, from the first Balance or Cheetah to the most recent Active 3 premium, can be good for a marathon. If running is your sport, probably a Cheetah or (much better) the newest Active 3 are the best devices for you between the Amazfit devices. I would avoid heavier models.
With the Active 2 Premium currently $93 on Amazon, not sure why anyone would bite on the 3 right now. I bought one yesterday as a potential shift from my current RingConn/Garmin combo.
Fair points. And yes, the Active Max seems pointless at the price point compared to Active 3
Seems very similar to the Max: same size battery as the Active Max, smaller screen, same brightness, and sapphire screen. I'd get this over the Max for sure. Only thing not to like is the two tone case and large bezels with tick marks.
https://us.amazfit.com/products/active-3-premium I was excited that the article said it had a bigger battery but that was a lie... It's about 33% larger than the Active 2 but the 44mm Trex 3 pro which has the same screen size was almost double.
Yes I stated its 33% more. You can directly compare the T-Rex 3 pro 44mm because the amazfit runs two screen sizes in the round form factor: A 1.5" 480x480 display and a 1.32" 466x466. The new Active Max 3 and Trex pro have the same screen size and the physical dimensions of the cases are very similar.
