Tracks almost correct - sleep tracking needs improvement though
Tracks almost correct - sleep tracking needs improvement though - I wake up many times and it does not track that so well

Not happy with this
Super unhappy with this product. The app is very difficult to interpret and isn’t giving me the fitness support I am looking for. In parallel the skin on the finger which I wear it on seems to have reacted and I can’t wear it anymore!

Quality not great
After one month charger/ring stopped working and connecting.

READ THIS BEFORE BUYING!!!
I bought the ring at such a high price, assuming that it would improve my health, but this device doesn't work without a subscription; that's a pure scam. Without the subscription, there is nothing you can do on the app!!!! AVOID!!
