Comes with what is shown. Ring + charger. Note that the new Gen 3 ring is going to require a subscription and the Gen 2 does not. There are things that the Gen 3 can do that the Gen 2 can't, but honestly those "upgrades" didn't seem important to me - I just have an addiction to new things.
I paid $300 for it, and that's what a new Gen 3 costs + the subscription.
Selling for $130 shipped.
If you are unsure if the size 9 works for you, I have the Oura sizing kit, so I could ship you the size 9 sizing ring to verify sizing upon receipt of payment. If the size 9 doesn't work, send the kit back and I will refund payment. If the size 9 works, then at that point I will ship the actual ring.
