Size 5, color bionic gold I bought this on Black Friday and wore for only a week, then decided a smart ring is just not my thing. It’s an awesome piece of technology and much better looking than an Oura ring, plus no subscriptions or costs included after purchase. I threw away the original packaging so I can’t return. Was able to put $100 toward it from my company so selling extremely discounted. The size 5 is true to a standard 5. I have small fingers.
