37 Degree L18 Smart Bluetooth Wristband Fitness Watch Mood Condition Breathe Heart Rate Blood Pressure Monitor Sleep Sports Tracker (Black)

I purchased this band from another online store which shipped it from China and took more than 2 weeks. I have been wearing it for about two weeks. It works as described - blood pressure once every hour, occasionally it could not detect my blood pressure a few times a day (today 2016/09/15 3 times). I did compare the data one or twice with an Omron blood pressure monitor I purchased from Amazon a few years ago and they were very close.Based on what I paid ($18.50), it is a pretty good band.

Excellent smart watch
