    I received it on release day. It’s only been a few hours since I have had it. But I love how there is no longer any bumps inside. It appers thiner, and well constructed. I love the silver, it looks so good with my white gold jewelry! So far no complaints!

    This rings tracks so much and more. Battery life is good for a 4-5 days. Don’t want it to get below 20% or it will damage battery.

    The ring was very accurate when comparing it to other tracking devices for fitness. I do believe the battery isnt as great as it was made out to be. Overall though, the ring is pretty good.
