    Ring will connect and sync to new phone when ring is on charger. Ring will not connect or sync to new phone on finger. Oura help is useless. Tried factory reset and all other steps recommended by Oura help to no avail.

    I don’t love it. After all the hype I was hoping to love it. I found it to be somewhat clunky. It was not comfortable for me.

    After having the ring for 5 months now it is faded on the bottom. I messaged Oura about replacing the ring but they said that is normal wear and tear for the ring. So if you workout and lift weights don’t wear it. Other then the worn out look it works perfect for all the health monitoring.

    I ordered the Oura ring 4 in gold size 5, received stealth size 8. I don’t know how they can mess it up that much. I spent DAYS trying to call, not one competent person to speak to. I had to go to the store twice, until I found a manager who was able to resolve my issue; remains to be seen because it’s due to arrive tomorrow, I hope.

    I didn’t love the Oura ring because I lift in the gym and it got in the way when picking up barbells and dumbbells. It is a good way to track many things for fitness but just didn’t work for my lifestyle.

    I bought as a gift on sale. I was told by the salesman that if it didn’t fit the girls can bring it in and exchange it. When they took them in they got the exact same rings but a smaller size. Well the smaller size according to the manager was a different “model number”. They charged my daughter $150 each for the two exact rings. Please be aware that Best Buy’s promises on prices has a trick to it.
