First problem is accuracy. I've used the product for a month and it has returned readings close to that obtained when intialising the bracelet with the cuff. I've just re-initialised and it has detected a big change in my BP. The device is not reliable if it can't detect major changes in BP between initialisation. Update 22/9/2025. After inital teething troubles the device worked fine. The sensor has now stopped working. As others have reported the customer service is unsatisfactory. Have raised a ticket through their robot and I've received a email acknowledgement. Watch this space.
