Donot buy it.
11 August 2018
Loads of problems developed within 2 months with this product:
1. The button on the band wont bring the next screen as it's supposed to.
2. Screen changes either on its own or it freezes.
3. Syncing with mobile is a big hassle. The app is buggy.
4. Very difficult to contact the customer care.
Bought this after using vívofit 2 for more than 2 years but unfortunately, vívofit 4 is a pathetic device.
