Get the ring sizing kit if you’re getting an Oura ring.
If you’re thinking of buying an Oura ring get one of these sizing kits. It lets you wear the different ring sizes on different fingers to test the fit in normal day use. Particularly if your fingers swell a bit in the heat this will really help you figure out the right size. You also get the price back against the purchase of one of the rings. Why did you choose this product over others?:It’s an original Oura product and therefore knew it would be correct sizes.
