I have it now for six months. As a construction, it is very good. A sturdy watch. It says it is waterproof. I tested it in the shower, it didn't suffer anything.... now for swimming, I don't know... It has very good brightness. The application has a Greek version but the translation is terrible. Also, the measurements are not so accurate... Its battery is average.... I charge it every three days with normal use...

The only time I am disappointed with a Xiaomi product. Although it is a good and sturdy device in terms of build quality and battery, it is below average in everything else.
The app is simply terrible, as if it is intended for children. The step, heart rate, and oxygen measurements are all over the place, with huge deviations, and the connection with the phone is constantly lost. You can find better for the same price.

I bought it a week ago and at one point the screen was shaking and easily disconnecting, and it doesn't accurately display the health and weather, and the other negative is that it doesn't have many applications on it.

The screen is very sensitive to scratches, it counts many steps, it does not measure blood pressure. But it has a bright screen and a good battery.

Difficulty in the TUCH screen, terrible application does not update from the clock while connected and generally difficult to use, not accurate measurements. Get a more expensive one instead (I have an AMAZFIT GTR2 and I'm very satisfied, I bought the MIBRO for a relative and I'm disappointed)
