Review on Expand Your iPhone and iPad Storage with SanDisk iXpand Flash Drive Go - 256GB Capacity by Cassie Marie

I almost gave it 5 stars. This SanDisk 128GB iXpand is much faster and more reliable than most cheap iOS iPhone flash drives. However, there is a bug/bug in the way this product saves data files and how the iXpand app works on my iPad Mini 2 and iPhone 6S Plus. It turns out that a folder with more than 50 video files is shown as an empty folder in the iOS app. I solved this problem by dividing it into several folders, each containing less than 17 video files. I hope this can help those who are facing this problem. Either way, it's a lot better than most products in this price range.
