My first smartwatch, so I chose according to reviews. I wanted 100m water resistance, at least some internal memory and a price of around 6k. Everyone can choose a suitable dial via the app, there are many of them. Unfortunately, I have reading glasses that I don't wear 24/7 in my eyes, so I haven't found a display yet, that I can read just fine, but as far as time goes, it's fine: )On the first charge they lasted 8 days of quite frequent testing, changing modes, playing music through headphones. It doesn't come with a cable, the charger is really tiny, magnetic, I put it on a solo cable. I haven't yet found a connection to youtube, spotify or radio, I guess anything can be downloaded via Zepp, we'll see. You can't answer a call, but on the contrary, SMS is fine to accept a photo sent from WA, you can answer back to WA by talking. I don't have Zepp pay yet either, but hopefully I'll find it in time.
price
internal memory
they are robust, yet light enough (of course, it's mainly plastic+steel regarding charging)
charger without cable
I guess the Zepp palliation takes some getting used to
the flashlight is there to light up the dial, a diode would probably be better
when the battery drops below 20% it switches to power saving mode and you can read almost nothing in the sun

Accurate heart rate measurement
It states at least 20 days of battery life. It lasts me about a week. But that's because I have a lot of sporting activities with GPS heart rate monitoring etc. But it's still decent

I evaluate them after 14 days - work, trips, bike, football
they fit perfectly and despite my very skinny hand they don't look big and don't get in the way
clear menu
great display that is very easy to see even in direct sunlight
good endurance
accurate GPS
a lot of sports I watch
options to customize menus, sports and in fact almost everything can be customized
the buttons are solid and the knurling is well thought out
notifications are great - the large display shows defacto everything. I can see that the photo came
the manufacturer added features that according to the forum were missing at launch - tap2wake, continuous heart rate measurement. they're still taking feedback and updating!
Sleep tracking - I kind of bought it for that reason too, but the watch misjudges when I wake up. if I'm still lying down when I wake up, it just marks it as sleep. MiBand 7 determined this exactly. I don't understand
different metrics are recorded for each sport. for example, in salove football there are no steps in the exercise, but I have to go to the step record and there I have to find out that I "walked" so much in those 60 minutes. I don't understand
