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.

Great battery life, and a great UI Easy to use UI in the app, and the battery life is great. Low profile form factor and durable manufacturing make it low worry for every day use and a breeze when you're sleeping.

I appreciate the app keeping me aware… I appreciate the app keeping me aware of my activities. Hopefully my life improves because of my healthy choices. Slight negative, the charge does not last 7 days.

I never got the refund for returned ring The ring was adequate for tracking vitals. However I was unhappy with activity tracking. I requested a return within the 14 day window. They said they would accept a return but asked that I wait for the new release which would address my issues. After months of back and forth, me requesting a return and them sending a new release, they finally agreed to a refund. I returned the ring and received a " refund notification" on 4/10. As of today 4/29, I have not received a refund.

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.
