I am not at all disappointed with the ring. Honestly, I didn't expect such precision, the QRing app is amazing! Everything is perfect. Whether it's my steps, stress levels, cycle tracking, or even my heart rate, which are completely accurate because I have my Apple Watch and it's exactly the same. Go for it, it's clearly the discounted version of an ouaring. I chose size 7 because I generally wear that size for my rings that I put on my ring finger, but I advise you to go one size up because my finger personally swells up when it's hot, when I do sports, and also when I sleep, so I would have been much more comfortable with size 8, but size 7 is perfect when my fingers are normal. I ordered size 8 in silver and I can't wait to receive it. Don't hesitate for a second to take it. It's a very good purchase.
