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.

Ring Benefits The people I worked with were very knowledgeable and understanding. They took the time to answer my questions directly and provided me with the best product possible. I am using my Ring for weight loss and maintenance. It keeps a detailed measurement of my steps, heart rate, and O2 levels. The ring is so accurate my doctor is using the data collected to help monitor my sleep patterns and stress levels. I recently had surgery, and the Ring is a great way to monitor my activity levels as I slowly gain more mobility and endurance.

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….)

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.

This ring is super comfortable This ring is super comfortable. The main reason to buy this one was to track the sleep. I was looking for other options but ringconn was unique due to the price, no subscription fee app and moderate design. The data and trend seems pretty close to my apple watch 9.I ordered the size 8, which fits perfectly. The only suggestion I can give them is to come up with some more options of the ring protector. It comes with 3 transparent one but I have recently ordered a different one from Amazon.
