Great Customer service
I have used a ring gen 3 Heritage for 4 years and something and I loved using the product. The battery of the first ring failed after roughly 2 years and they changed it for free even though there was no warranty anymore then when the replacement failed again after 2 years or so, they gave me a discount code of 200 euros towards a new ring so I bought a gen 5, they also gave me 3 month of membership for my trouble and it was a breeze to do all that, I didn't even complained, just told the AI assistant that it felt my ring was not holding the charge anymore and it ran diagnostics by itself, put me in contact with an agent and I had a clear solution in days. Apart from that, I feel it is always correct on sleep measurement and as I can't wear something on the wrist I love this, so light you always forget you're wearing it.
