### ⭐ Waste of money!
*by M***S on 27 September 2025*

Total waste of money! Zero after sales service and their system is compromised. Nothing against the seller but the issue I have is with Oura. My card details were leaked after paying for the membership and there is no support at all from oura neither is it very easy to speak to a human and get a resolution. I am stuck with a 1200 AED useless piece of junk
