I have had the ring for a week now and it works perfectly. The instruction manual is clear. Charging is fast and the battery lasts at least a few days. I don't have any skin reactions from the ring, so the material is good. The LCD screen is clear and it keeps track of steps and sleep well. It is easy to connect to the iPhone via the JRing app. I would advise choosing 1 ring size larger than your own ring, as it is a thick ring. Definitely worth buying for this price!

I had some initial doubts, but this completely exceeded my expectations. It works perfectly. I’m really happy with the results.

Item received very quickly. Well packaged works excellent. Would recommend this seller to anyone for a hassle-free sale. Very impressed all of the functions work correctly. Display is fine.

Works perfectly, product matches the description perfectly. Very easy to wear, not heavy and doesn't irritate the skin. A nice discovery.

Excellent product and excellent price. It calculates steps, heart rate, oxygen levels, sleep hours, and you can control the brightness. There are many options in its dedicated app. Thank you 👍🏻

I ordered on July 21st and it arrived on July 27th. It has a smarter size than expected and feels great to hold. I don't care about the weight at all, so even wearing it won't feel uncomfortable. The connection with the smartphone was easy, and there are no difficult operations, so I think it's good.
