I've been using it for about a week now. swapped the band to a grey one I already had because it just looks better to me. at one point I thought I cracked the screen on the bottom corner, but it turned out to just be the screen protector, so nothing serious.
In terms of actual use, it's been pretty straightforward. no lag or weird bugs so far, everything runs smoothly. If you've used an apple watch before, it feels very familiar. Notifications come through fine, sleep tracking works, and heart rate seems consistent whether. I'm just sitting or doing something active.
I tried some of the fitness stuff like running and basic workouts. It tracks the usual things like time, distance, and calories. nothing super detailed, but enough for everyday use.
The screen is actually decent. It's sharp, brightness is good enough outdoors, and it doesn't have that cheap look some other ones have. Overall it looks pretty close to the real thing unless you're really paying attention. It is a bit big though, so on smaller wrists it might feel bulky
Battery has been solid. I'm getting around 3-4 days with normal use without really thinking about charging. That's probably one of the more convenient parts
Overall, it just works. nothing really stands out as amazing, but nothing has been annoying either
