Well! First of all, I have had it for 1 week and I can distinguish its characteristics.
The smart band-watch is very reliable because it is neither a band nor a watch. Essentially, it is more than just a smart band. It has many modes such as:
Many sports that you can choose to track: Water sports, Outdoor activities, Workouts, Dance, Combat sports, Ball sports, Winter sports, Recreational sports, and more...
Many measurements with or without Bluetooth:
Degrees Celsius in your area, Steps, Posture, Calories, it also tracks sleep (What time you fell asleep, what time you woke up, and how many hours you slept), Heart rate, Blood oxygen, Stress...
Modes:
Flashlight, Alarm clock, Stopwatch, Selfie which you can take photos from your phone by pressing the button that the watch function will display. Cycles (recorded with Bluetooth), Music (you control what music you listen to and how loud you listen to it from the watch with Bluetooth connection when the phone is in the Music app. Find your phone, Timer, Notifications, Screen brightness, PIN setting, Do not disturb, Bluetooth disconnection reminder, Band screens that you can choose by downloading them from the Mi fitness app (which you need to install for the watch). In one photo, I see a different wallpaper for the watch that I set... Vibration, System, About the device (All the settings I mentioned from "Screen brightness" to here are in the settings).
The battery life is excellent as it is only at 42% out of 100% after 8 days of use without charging.
I think this watch will meet everyone's needs, it is excellent for only 35€... a bargain...
It is worth the money and more.
For those of you who mention the strap, I didn't have any issues with it...
I recommend you to buy it without any doubt.
EDIT:
I noticed a new feature that you can choose your own photo from the files and your gallery (screenshots, photos) as a wallpaper on the watch's band screens...
After 2.5 months of use, the watch continues to be flawless.
EDIT 2:
⚠️ Unfortunately, from what I saw, the reviews about the strap were not wrong, as every slight movement it receives easily comes undone and it is a bit annoying, so those of you looking for this watch should keep this negative aspect in mind! That's why I stuck it with instant glue since it wasn't important for the charging port to be accessible and I haven't seen any issues with the strap again. (The issue with the strap is not at the end where it fastens in the holes but at the point where it fastens with the main watch). I don't know why they made it possible for the straps to come off in this watch since it doesn't charge from their connections but from below
