I'ts Always Good To Try Before You Buy!
Nice to use at your leisure and get used to, get the best comfy fit as the ring is wider than a normal ring. Good ring sizer all round, I got it on sale so good value for money.

BEWARE - size for Oura 4 is different to Oura 3
Don’t risk guessing your size - I have used an Oura Ring 3 for over 3 years now and decided to upgrade. My Oura 3 size is a size 13, the Oura Ring 4 sizing kit showed I needed a size 12 for this ring, the fit is different. I purchased the Oura ring 4 in size 12 and it fits perfectly and very comfortable. Also this kit was £5 and gave me a £10 discount on the ring so a no brainer. Don’t risk getting the wrong size, get the kit and wear the plastic blank for 24hours - you can then be confident of the right size.

Discount not sent through
It appears this doesn’t come with any discount off a final purchase of a ring.

Il kit di misurazione è molto pratico. Misurare il dito prima di acquistare l’anello è semplice e preciso, così ho preso la misura giusta al primo colpo. Consigliato a chi vuole evitare errori e ottenere il massimo dall’Oura Ring
