Due to the sleek looks, I have decided for the Vitality. Unfortunately, I had bad luck and caught a defective tape, but a very nice and fast contact directly with the manufacturer took care of quick remedy by Express. The band wears well, is very discreet and I especially the vibration alarm with which I now also like while working quietly to my appointments am reminded. Other features I can not comment, but the connection with the app works without problems (Samsung Galaxy S4).
