it's very beautiful and got powerful app i dont argue, but i used Jawbone UP (not 24) and it's not last for a year. even i return and claim a new one. it's still came with battery drain issue. so if you can take the risk of UP24 so just get it. i change Garmin Vivofit right now. on itself it's reliable device. connecting to other apps still not good. but the always on clock function very useful.
