Review on GOKOO Smart Watch: Advanced Blood Pressure & Heart Rate Monitor, Fitness Tracker with Music Control, Sleep Monitor, and Customizable Dial. For Men & Women, iOS & Android Compatible. by Jaya Walsh

Sorry but please don't buy this watch! The looks are gorgeous and the app is pretty good, with several interesting watch faces to choose from. The problem is the accuracy or lack thereof. I'm an exercise person who really relies on heart rate and blood pressure. This watch reads a heart rate of 60 (mine barely hits 59 when resting) and 60 seconds ago the heart rate is 115 just when sitting still! Blood pressure is really a joke. 115/63, then 130/80, back to 123/70 and finally 142/80, just sit still! So if you want the accuracy of these features, as I think we all do, then DO NOT BUY this watch.
