This is a Gen 4 Oura Ring in the brushed silver finish, size 7. I have owned the ring for about 8 months and recently got a replacement because the battery in this one did not perform as expected. This ring typically lasts for about 56-72 hours on a charge, so you will realistically get 2 nights of data from a single charge because once it drops below a certain charge level (I think 20% or so) it may not retain overnight data. It has scratches from normal wear and tear. Otherwise, it works great and I haven't had any other issues with it. I have owned Oura rings since Gen 2 and would say that this brushed silver finish does scratch a little more easily than the prior silver finishes, it doesn't really bother me because it's a tool but just be aware it is not in perfect condition! I'm open to offers. Box, cable, charger, and ring are included.
