Full disclosure: I have an iPhone and an iPad but am all about good products. I've been looking for a multipurpose fitness band/watch for some time now, something that I could use not only with my runs but also with my other sports activities. Lo and behold, I stumbled upon the Band and was able to get one two days before I completed my first marathon yesterday. At first, I was a little nervous with all of the mixed reviews, but I have to say, it held up very well during my run! I had GPS turned on, so the battery was low by the end of the race (more than 5 hours later), but it hung in there like a champ. It did well measuring my distance, heart rate (though I had never had a heart rate monitor before so I couldn't compare the accuracy), and other stats. I loved the haptic feedback I got when I completed a mile, and the final stats (especially time and pace) were much more accurate than MapMyRun, which I used just for comparison. Feel free to ask questions!
