  • Adds bulk and weight to iPhone. Extra storage is separate from internal storage. Pricey
  • Belowaverage battery life; Inconsistent app; Slow to sync photos
  • Bulkier than most iPhone cases, iPhone 5 and 5S only, iOS' restrictions limit how you can interact with the case's storage, Recessed headphone jack makes it hard to plug in headphones without the small, easytolose accessory, More expensive than most cases
