It arrived very quickly and well packaged, I charged it and set it up, and it seems to measure correctly when you are more or less tired, as well as steps; it has a delay of about 10 seconds until you notice that you are walking. I haven't tested the rest of the functions yet, the design is discreet and it's comfortable; the screen is easy to see due to its brightness.
I don't recommend this ring, it only lasts 19 hours
The colmi r12 smart ring arrived very quickly and was extremely well packed. It is honestly one of the best gadgets i have ever bought.
Before choosing this model, i did a very careful analysis to find a highβquality chinese smart ring, and the r12 was an excellent surprise. The battery life is great, the tracking accuracy is solid for daily use, and it is very easy to sync with android via the app.
I am very happy with this purchase and definitely recommend this product and seller.
Looks good, quick delivery, good value.
