Happy but missing activity tracking The ring is comfortable and I like it more than wearing a smart watch. The battery in my case lasts around 6 days and the measurement of vital signs works good thus sometimes the sleep stages are not correct. I am surprised by the robust surface that is not as sensitive to scratches as I expected. When charging I notice a burnt smell which I already reported to support

Overall pleased with the device. The measurement ring and actual ring were delivered on time and arrived as promised. Setup was easy. The software is easy to understand. Device has worked as promised since I got it. It's great for sleep profiling, and stress rate when I'm not exercising. HR is not tracked well during vigourous exercise.

I ordered three rings I ordered three rings. One of the ring size was not accurate. There’s no way to return the ring. I was told that I cannot return the ring because I chose the size. Please note an American seven fits me perfect this particular rain fits on my pinky finger horrible horrible service

Thus far really good experience Thus far really good experience. So many details. How does it know? It distinguishes when I’ve gone to the bathroom versus when I am awake so accurate. It measures my stress levels and gives suggestions to help improve. You have running in your app when are you getting walk? I like that I can measure my heart rate and my oxygen as I am always congested.

RingConn is an excellent piece of tech RingConn is an excellent piece of equipment. That product does an incredible job and my wife is so happy. So why only three stars, ordered this over a month before it was needed, the size rings turned up 10 days of ordering, order the size with two days, had to double check with an email as it was not clear it had been order. Then if took three weeks to arrive from of all places, China. It arrived over two weeks late but had been sold as a US piece of technology. Not impressed it was a gift with plenty of time to arrive.
