This smartwatch has a wrist-up color display which is very sensitive, its band is easy to be replaced. Fitness data sync is fast. Different sports are supported. The smartwatch is also a remote shutter and it can be used to control music! I also bought another one for my little brother. The length of the steel band can be adjusted very conveniently. Compared with my friends’ AMAZFIT, Alfawise H19 includes all the functions it has, so evidently, the latter is a better choice.
