Suunto M1 heart rate monitor is a good heart rate monitor. It looks pretty good . Looks are awesome . Design of this smartband is not so much unique and good. Design is not new but changes are made in the design of this smartband. But the build quality is very bad. Very cheap material is used . On the Second day after purchase its chain grip is brokened. So not satisfied with its material used for making . Features are also not so good. It is not user friendly. Battery life is very good. But not a value for money product for me
