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.

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.

Great tool to monitor my health I have been able to use the information on the app to understand how things are working with my CPAP. Also, after a recent surgery to see how low my O2 level was during the night after the surgery. I wish you had put a mark on the outside of the right that shows it is positioned correctly for reading. I tried myself, but nothing seems to stay on the coating. If there was a mark on the outside of the ring that would be towards the palm of your hand it would be easy to know that it had not twisted around too far.

Overall this ring is great! Overall this ring is great!! I do wish there was some sort of gauge /alert on the actual ring, when the battery is running low (vs having to check the app) Also more ‘activity’ measuring is a must! That is being worked on (i.e. measuring output of running, aerobic classes, Elliptical, Pilates, Biking….)

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.
