Great service! Incredibly quick delivery. Even when it went over the 48hour delivery time I contacted them and they organised a private driver to deliver to my new address before leaving the country. Really happy with the product also.

Oura Ring 4 Sizing Tips
Your Oura Ring sizing kit will help you select a size that ensures optimal accuracy and comfort day and night.
1. Choose your finger
Your Oura Ring can be worn on any finger. We recommend the index, middle, or ring finger for optimal performance.
2. Test the fit
Your Oura Ring should fit snug and secure on your finger, but not to the point where it's uncomfortable. Try making a fist to ensure there are no gaps between the ring and the finger. Wear the sizing ring with the size number visible on top of the hand.
Take your time to find the perfect fit, we recommend wearing your sizing ring for at least 24 hours before confirming your size.
3. Confirm Your Size
Once you're feeling good about the fit, place your order for the correct ring size
