Order 1 size up!
I’m usually a ring size 7. But it was too small had to return - I’d recommend getting 1 size bigger, the ring is comfortable, light and looks good on. The app is very good. It’s not gold - more of a rose gold/bronze colour

I am fully satisfied with quality and options.
Excellent Smart ring with more then 10 days battery life and free Application. Good accuracy, easy settings and democratic price.

works great
I'm positively surprised by the RingConn ring and can truly recommend it. It's very comfortable to wear and does a great job tracking vital data. While the current selection of sports modes is still quite limited — so it doesn’t fully replace a sports watch — it’s excellent for overall health monitoring. Looking forward to future updates with more activity options!

Simple, effective, and exactly what you need. It’s a sizing kit so there’s not much to overcomplicate but it does its job perfectly. I wore the sample ring for a full 24 hours, which gave me a really clear sense of the fit and overall comfort throughout the day and night. That trial period made a big difference, and I felt confident choosing my size. The fit ended up being incredibly accurate when I received my actual ring. Overall, the kit delivered exactly what it promised and made the whole process easy and reliable. Definitely a worthwhile step if you want to get the right fit the first time.

これを買ってから製品を購入しました。店舗でもサイズを確認したのですが、キットで何日か装着するのとは違いました。

Gran anillo! Excelente compra, primero queria comprar el Oura hasta que encontre este ya que se me hacía loquisimo pagar una suscripción para acceder a mi información Me marca sueño, mis pasos, mi actividad y todo lo necesario, hasta temperatura corporal y HR. Si ered mujer te trackea tmb tu ciclo! La bateria le dura 1 semana sin problemas y ya llega a 20% te avisa cuando tendrás que cargarlo. Yo que no quería un reloj tosco ya que no soy atleta este me ha funcionado perfecto
