The functions are fine, although I can't really compare whether everything measures accurately and how accurately, but the graphs look believable.
The app is ok, there is a huge selection of sports to track activities, but it's very easy to forget that I turned on tracking and then it tracked my "walk" for 5 hours.
I have not tried ring payments.
fast charging
under about 2 weeks the top layer cracked in 2 places, but it does not affect the function
only syncs some data with Google Fit
the application is harder to use on a small display (3"), the graphs are almost not visible at all

really long battery life, I charge once a week
reliable measurement of steps, sleep, heart rate and body temperature
sync with Samsung Health via Health Connect
light, after a few days I don't even notice it anymore
waterproof, I don't take it off in the shower
simple, clear application, in Czech
charging time approx. 40 minutes to full
NFC payments work even when fully charged
great price for being the first of its kind - combining smart ring and pay ring into one device 🙏
susceptible to the slightest scratches and drops, within a few days there are visible scratches and abrasions
fragile outer layer, after two weeks of wearing and functioning with it, there are already 2 cracks visible on it, from edge to edge, but the functionality does not matter, just a cosmetic defect at a really close look or swipe
sometimes during payment problem with some terminals, it is necessary to take off the finger and attach the whole circuit
when the amount exceeds 500, it is necessary to enter the PIN as with a regular card (I would expect it to be like with a mobile phone, without the PIN)

According to the Sizing kit I chose size 13, but after the ordered size arrived the ring is looser. Subsequent measurements with a slide showed that the ring was slightly larger. Unfortunately, I have to return it and buy a smaller one.

The ring measurements are overall good. However, the main reason i purchaed this one instead of other brands was because the material. Niceboy claims that the zyrcon ceramic material makes this ring the most resistent ring on market but after just 30 days from its purchase, part of it already break. I’m taking very good of it, removing it when i shower and/or wash my hands, yet, it just break out of nothing after just one month. Another creepy piece made by Niceboy
