Had no idea I �needed this watch! My husband encouraged me to get it and try it out. I did not think I would find it useful, but I've worn it everyday since and love it! I love to see my fitness progress throughout the day.. how many calories I've burned, how many minutes of exercise I've done, and how many hrs I've been standing. It has definitely encouraged me to be more active! I also use it to ping my phone when I've misplaced it. I also love the fact that it alerts me when I have a text or call, so I don't miss anything important. So while not 100% essential, it is a luxury that I have thoroughly enjoyed and benefited from! I encourage you to try it out for yourself too!P.S- Fun and simple to change out the watch bands as well!
