This is my review as per communicating with supplier. This watch does nothing you claim it to do. Only HR? For blood pressure, oxygen sats nothing happening. Your instructions are totally lacking. I can’t even figure out which toggles dies what. I am going to send this back unless you have answers for me. Please advise. Since fiddling around and having had replies from the manufacturer the following: It does manually take the blood pressure and SaO2. It can’t be set as an automatic cycling feature though. The HR is continues, so us the pedometer. It alerts for messages and can be read with select button left upper. Started wearing it now and hope it will reveal some more functions. Not bad but for the price but wondering if there is anything on the market that does the above mentioned auto cycling?
