What customers say about "Features"
SanDisk iXpand USB/Lightning Flash Drive
  • Large capacity and transfer rate. Convenient and practical
  • I doubt I'm using this to its capacity, as I just store data on it and don't stream music or movies. Even so, it's nice to have everything we own in one place and room for ten times more.
  • The product itself is great. USB 3.0 is blazing fast and the iPad recognizes the device as soon as it's plugged in.
  • It would be nice if the USB side had a protective cover to keep out dirt and foreign objects.
  • Unfortunately! Can not protect saved files with a password.
PNY Duo Link Sync & Charge 32GB Metal Gray USB Flash Drive
  • Great product for removing a bunch of photos and videos from my iPhone to my computer.
  • Really simple to use. I backed up my iPhone in just a few minutes.
  • This sync and charge device is an easy way to back up or transfer pictures and videos from an iphone as well as charge the phone.
  • It was easy to transfer the videos and photos from the phone to free up space.
  • It also works fine as a thumb drive to back up files from the computer.
