Perfect
Fast delivery. The ring fits. Exactly as in the photos. Very nice design. Body temperature, blood oxygen and sleep measurements are not accurate. I check them on my smartwatch and the readings are different. But as an additional stylish accessory i definitely recommend it! Thanks to the seller!
It arrived earlier than expected. The size fits me perfectly according to the chart, although I have a slightly thick finger joint it barely fits, but once worn it feels very comfortable. It still fits a little loosely on other toes. When installing it, my phone didn't detect it, but I restarted the phone and it worked perfectly. I've been using it for a week and I'm very satisfied! The battery lasts several days, and it is very accurate when taking measurements. The only thing I have doubts about is the step counter, which doesn't seem very exact to me, but it's not the main thing for me. However, when I use it in sports mode (there are many sports options), it improves quite a bit. Very satisfied with the purchase!
Working ring. For its price, it performs its function well.
Love so far. Fits as measured. Much more accurate than my smart watch. I pray it lasts for years. Worth the buy
