Elegant multifunctional smart watch
I got this TOZO S4 smartwatch 1 month before .It is elegant ,multifunctional and user friendly with a reasonable price. It helped me with my health issues like sleep study, heart rate and oxygen saturation,mainly when using TOZO Health app, but I hope to get another app. for other functions of the watch.I had an issue with the watch, but the customer service helped me quickly to solve it.

Watch does not charge after few days.
I have take this watch 3 months back. Initially it worked well and slowly it started acting wearied like Bluetooth gets disconnected automatically and after few days phone stopped charging. I even tried with the new charger and yet it does not charge. I would not recommend this to anyone. Its a BIG NO to this watch.
