Top critical review
Faulty piece received once and performance not good at all.
20 December 2018
First product recieved was faulty. It was showing error to connect original charger while charging. Battery used to heat up while charging. It took more than 5 hours to charge full. Battery inside the watch or charger was faulty. I replaced the item. After receiving replacement item, it was found that wrist belts were connected wrongly. I used it for 4 days. Following are the observations about the performance.
1. Battery backup is very unpredictable. For first charge it worked for 1 and half day. For second charge battery lasted only for 7 hours. For third charge battery was again normal.
2. It can not measure steps correctly.
3. It stopped measuring heart rate on 4th day.
4. Music app drains battery even after closing the app.
5. Does not measures floors climbed after 9.
6. It tracks workout while driving at 80 kmph and ask to keep up the pace.
7. After logging calories burnt on 2nd day upto 1891, next day morning it showed only 39 calories burnt.
8. No log of sleep record maintained.
9. You can only reject call as it does not have speaker.
10. Pressure measurement and altitude measurements faulty.
11. After so many issues did not dare to check water resistant quality. Might have been the last day of the watch.
