Fairly good
Conclusions: I bought this smart bracelet and a different one at the same time from Tinydeal. I like a lot of things about this one. It is not that neat on my wrist compared to the other one I bought, and I don't like the narrow text that is squashed up, so that the time is on two rows. What I do like about it, is that it a great app that you put on your phone. I love the ability to set the BP and HR to automatically take readings every half hour. So at the end of the day, just open the app on your phone and you can see on a neat graph what your heart rate and blood pressure has been doing during the day. I have found BP and HR to be fairly accurate.
Dislike: narrow watch face, ugly text, a bit uncomfortable with stiffer bands than the other I bought.
Like: The good app that synchs with it, BP and HP auto recording at intervals, battery lasts long
