Bests & Worsts Reviews from Amazon

This is my 1st smart watch, after compared with Samsung Active 2 and Fitbit Versa 2 I decided to purchased this one. Pro: 1. Price is good. 2. Long battery life, still have 69% after 3 days usage from 100% full charged ( auto sleep tracking and heart rate detection set to 5 min, and app alerts ) 3. Light weight no problem wear during sleep at night Con: 1. The weather need to improve on the Amazfit app, unable to locate the city i live, it detected nearby city with incorrect temperature. The app also won't auto detected my work city. 2. The sleep monitor will not track afternoon nap, I took 2-3 hours sleep in the afternoon and the app has no data. 3. Only 2 default watch face are customizable. 4. No ECG 5. No user guide manual, download from Amazfit or Amazon Update 9/3/20 After 6 months of usage, I noticed the battery drain so fast, fully changed before bed time, after 6 hours 76%. This watch usually last 10 days per change, not sure if this relate to last update. Contacted Amazfit support hopefully they can figure out the issue, otherwise, this will be my last MIC product.
