This ring is great — this is the second one I buy. I also bought one for my wife. I compared it with a pressure monitor and it's very similar, same with the oxygen. Very satisfied.

I've only had it for an hour. But it seems to be good quality, and the parameters appear to be working fine.

For me it's mainly the blood pressure feature that I wanted, and it really delivers. Even though it shouldn't be used as medical advice, it still gives you a guideline. I now have three of them

It's a good smart ring; if you already have a baseline blood pressure reading it's fairly accurate. The sleep tracking is a bit off, but overall it's very good for the price and you forget you're wearing it. Very happy

The item arrived in perfect condition and matches the specifications. It was well packed and arrived before the estimated date — exactly 11 days. The ring was a bit small for me but that's not a problem. The item is good quality; I'm satisfied and recommend the seller. Thank you very much

I liked the ring a lot, but I should say it didn’t come with a charging case — just the cable.

It's okay. However, I chose the wrong size, but that's not the store's fault. I can only suggest listing the internal diameter for each size in the product listing.

Works. A bit thick.
