It took me a month to see and use its functions.
Purely a personal matter: I don't like that it is elongated, I would prefer it to be square.
Now, onto the objective aspects.
First of all, because it is Huawei, if you have a different mobile brand, you need to download the company's app store in order to download the application. It's nothing significant, it's easy.
Positives:
Many useful functions.
For me, who works at night, it is important to monitor my sleep during the day.
It has this function, the 24-hour monitoring, but it only tracks naps, not sleep.
It monitors oxygen and stress levels.
You can see the songs you listen to on Spotify, but not for podcasts. (For me personally, it doesn't matter because I don't use this function, but I mention it for someone who might care.)
There are several faces that you can use, both free and paid. However, it's not the wide variety that I had on my old Amazfit Bip. The most useful ones are paid (useful in terms of displaying all the information) and the prices are mostly very low, around 1 euro. The most expensive ones reach around 4 or 5 euros, if I remember correctly.
You can adjust the brightness and vibration strength, how many seconds the screen will be bright, and set up the layout for the additional options.
You can see notifications for calls and messages. I think you can answer calls from the watch, but not speak from it, I'm not sure because I haven't used it.
It remains connected over a long distance. If you are in an apartment building (where the walls are thicker), it disconnects at around 7 meters. However, if you are in a company with mainly false walls in between, it disconnects from the 2nd or 3rd floor and above.
Negatives:
Objectively, the negative aspect is that the battery doesn't last many days. At most, 3-4 days. But the charging is fast, especially if you have a fast charger from a mobile phone. But even with a regular charger, it still charges quickly.
Now, onto more subjective aspects: The screen saver is negative for me.
And let me explain: I want to see all the information immediately (steps, kilometers, etc.). Unfortunately, this is not possible because all the screen savers only display the time, and some also display the date. So I have to press the button to see the main screen.
And even though there is a saver after a certain time, the screen completely darkens and nothing is visible. For me, this is a flaw. At first, it bothered me a lot, but now I have gotten used to it.
Finally, something that I noticed people asking about here and on other mobiles, and it has become common lately.
The mobile constantly disconnects and you have to enter the application to reconnect.
The only solution I found is as follows: I locked the application and it remains permanently open.
You tap the square on the mobile and it shows you the open applications. You press and hold the application you want to lock, and a menu appears with a lock icon. You press it and the application locks and remains open, so you receive notifications. I haven't found anything else. And this happened with both this watch and my old Amazfit, so it's not a watch issue anymore, but a mobile issue, because we're talking about the same mobile, with two different watches from different companies, so different applications.
At the price I found it for, 54 euros, it is very good.
Huawei is a brand that I like in smartwatches (I had older ones too) and I consider it reliable.
