I?ve had no issues with battery life either, I?m still going on a single charge since I got them and have used them for approx 4 workouts so far this week. This came with the rack but NO hardware was included! I used them with my old apple ear pods and they totally stayed in my ears. I used gloves every time I packed it because that plastic that lays over the zipper hurt/cut at my hands. Good for all year around. THANKS FOR WASTING MY TIME! We live in a modular home now and I do not feel like having holes in wall at this time. I dont think she will be ordering any more FitFlop Sandals based on this experience. Amo que tengas ruedas. 5 or 11, and since 10.
