## Description

Why the heart rate monitor not indicate immediately？ Some buyer will ask why I cannot get the heart rate monitor to work? We will make explain,bpm is indicated heart rate and mmHg is indicated blood pressure We use a green light sensor, in principle, when the skin contact with the sensor on the bracelet will be issued a beam of green light to hit the skin and to check the blood flow through the hand. When the heart beat, if the blood flow increases,the absorption of green light will increase,but heartbeat interval will be reduced. So it must be measured for a period of time to give relatively accurate data,if the data indicate immediately that errors will much more bigger.That's why will delay to indicate on the watch,but the data can be indicated immediately on the APP. How long does the battery last? 1.If you didn’t open any function on App,the battery last 7-10 days  2.If only open some function on App,the battery can last 5-6 days  3.If open all the function on the App,like Heart Rate Monitor,Activity Tracker,Sleep Monitor and Alarm,Sedentary Reminder and Other functions,the battery can last about 4days  Function instructions: 1.Notification Alerts - Alarm alert, call alert, sedentary alert, etc, by silent vibration2.Multiple motion mode - Running, swimming, basketball, badminton, etc3.

## Customer Reviews

### ⭐ Looked better than it was - returned for a refund
*by H***N on 24 November 2017*

Lasted 4 hours before it shut down and refused to charge so returned.

### ⭐⭐⭐ Good and Bad in both extremes.
*by C***T on 9 February 2018*

I would like to review this item from two angles, four stars on the bright side and minus four on the other. It seems to work well in terms of its HR and blood pressure monitoring, it notifies me promptly when I get a call, SMS or something on Whatsapp, and the sleep function is neat. But I bought it for one thing only - swimming, which it CLAIMS to cater for. But when I went into the pool with it, the sensor on the front seemed to respond to contact with the water in the same way it would the touch of a finger. So during an hour swimming, the watch went berserk... It changed functions dozens of times, started, stopped, switched itself off, on again, every few seconds, all because it thought that the water touching the front was a command from the user. And there was a lot of water in that swimming pool today. Therefore, if I am ever tempted to check my blood pressure, I do now have something that can do it for me. But I still do NOT have a device which can track my swimming.

### ⭐⭐ Two Stars
*by M***S on 25 April 2018*

not suitable for swimiming
