  • Cool but battery life is a lie

    The ring is really cool and gives you a lot of data if you’re into metrics but they absolutely lied to you about the battery lasting eight days. The battery is based on the size of your ring. Bigger rings will have bigger batteries and smaller rings will have smaller batteries. I’m using the second largest size ring and I get four days maximum which is only half of the claim eight. I have the silver colored ring and it scratches insanely bad.
