Great product

My son is loving this ring. He wears on his middle finger and is loving the fit. He feels like he is getting great information to help with his health journey.

The item was easy to pair and provided great information. For me, it was uncomfortable to wear and made it a bit difficult to do daily tasks. While I am more tempted to wear a ring more constantly than a watch, this is a bit uncomfortable.

Overall, this ring is a great concept. I just don't think the technology is there yet. It's an awesome concept, but the battery does not hold charge for more than a day after using this smart ring for three months. It does not want to connect and I do not believe it's very accurate in the sleep tracking or steps. It also left a white ring around my finger and not just a tan line.
