It’s exactly what you can expect for 10 eu
Its working,does its job well
Good for daily activities but Definitely not for sweaming .

For the money I paid, it naturally broke immediately. If you are interested, buy an economical one (like this one) and see if it serves your needs, and then buy one that will meet your needs.

Unfortunately, it was a purchase failure.... It didn't work correctly from the beginning and completely broke down in the first week.

The synchronization with the phone is constantly lost. The measurements are terrible. As an example, I was sitting on a chair and trying to make some adjustments and it was loading the step counter. Without any movement, it had already recorded over 1000 steps. As mentioned, the lighting is also problematic and you can't see anything in the sun. It is simply for us to see the time, and even that is only indoors!

For the 3€ I got it from China, it's good. I only wear it when I do heavy work to see the time. The rest of the measurements it has are laughable...
Also, the strap and charger are the same as the mi band 3, so I have spare parts too!

The battery needs to be charged every day. The build quality is mediocre as the top part of the screen is almost falling apart. Money wasted. I do not recommend it for purchase at all.
