UPDATE - It is 4 days later and we now know that with the proper app installed on an iPhone you can first track the iTrack by GPS and find out where it is - IE your buddys house, Grandmas, church, the hardware store, corner of 5th and Main, Etc. Slip off heel Im no audiophile, but Im certain this will do well for parties, the pool, skiing, picnics, etc. I looked ok in it but it felt quite loose around the waist. They were a good flip flop made okay I did not have them very long and they went in the mud I did that several times during the first five minutes. My final review has changed from 1 star to 3 stars! Uncomfortable. I could have gone for a cheap $50 knock-off pair. 5 charging cables (works excellent, no problem).
