YHE BP Doctor Med, Blood Pressure Smartwatch with Dual Patented Cuff, Wrist BP Monitor 24/7 Stress Monitoring Sleep & Sports Tracking App for Android & iOS (Gold)

I will keep the two I bought for the blood pressure function. Sleep tracking is so random it is useless has not gotten even close in about 2 weeks most days recorded nothing. Same results for my wife.

This is the second (or 3rd counting the one I returned) of the YHE BP Doctor watch I bought. It is beautiful to wear but the battery has a short life span. Without testing for BP or anything, half of the battery life was gone in a day! For the record, I didn't do anything else with it other than to check time - no receiving of messages, no music, no phone or anything of that sort. Not good enough considering the purpose of the watch and the cost. I hope they can improve this battery issue and other features of the watch. At this point, I am certainly not encouraged to buy another one.
