Purchased in March 2023, See wear and tear on images (I actually prefer the more worn look on these rings). 
This ring doesn’t hold a charge like it used to - which is why I’m getting rid of it. Selling as is with current battery function. The battery charges to 100%, and lasts about a day and a half, ~36 hrs , unlike the newer rings which hold charge for up to 5 days. Could be good for you if you’re wanting to try these rings out, without forking over the 400$ to buy a brand new ring. Comes as is, without charger/cord so you’ll need to provide your own. Available for purchase online. 
Happy to answer any questions. Open to offers. There are things you can do to get the most out of the battery: (from Oura site) :"Follow these tips to get the most out of your ring's battery life. We recommend keeping your ring’s battery level above 30%. Having your charger on-hand (such as in your purse, car, backpack, or at your desk) can help you get into a routine of charging your ring for a little bit each day. Consider charging your ring during natural periods of low activity, such as when washing dishes, typing on your computer, showering, cooking, etc. Enable Airplane Mode If you’re looking to get the most out of each charge, we suggest placing your ring in Airplane Mode. This turns off all Bluetooth communication between your ring and phone, which can help to conserve battery.
