The screen constantly flickers when it is turned on. The strap is okay, but the clasp was so tight with the watch that it pulled and damaged the plastic of the charger when I took it off to charge it.

In the beginning, it was good.
After a few days, the battery started to drain quickly.
When I charged it, it overheated and my child couldn't wear it afterwards because the temperature on the sensor was too high.
No comparison to the Xiaomi Mi Smart Band 4C, which I would highly recommend for the same price.

Personally, I am not satisfied with this product.
1) The Bluetooth connection does not change the time and does not communicate with the mobile phone.
2) Its menu does not have many options and I cannot reset its measurements.
3) The measurements are inaccurate... very inaccurate measurements. For example, it counted steps at my work that I did not take.
4) The battery lasted only 28 hours.
5) The instructions are inadequate and do not help at all.
I emphasize that this is MY OWN opinion.
For its price, it is relatively mediocre.

For something simple, it's fine. You get a taste of what an activity tracker means. I don't know how accurate its measurements are. However, it does count the steps correctly. I don't think it's accurate for measuring blood pressure. The strap is somewhat fake. It's not made of silicone but plastic. Its battery life is short. I really liked the app that connects to my phone. I don't regret buying it. It's fine for someone who doesn't have high demands :))

For a first encounter with activity trackers, it is very good. However, if you want something that fully covers you, I would not recommend it.

I bought it a week ago.
It's good for €12.90.
Overall, it has inaccuracies in all measurements.
Especially in pressure measurement.
The entire screen is not touch, only the central navigation button is.
You get what you pay for.
In a little while, I'll go for something more serious and expensive...
