The reader is a tiny white plastic gizmo that plugs into the charging slot on an Android device. If the device is running Android Jelly Bean 4.1 operating system or higher, it immediately recognizes that it has USB storage. Users can transfer photos and other files from the SD card to internal memory or use it to play music or videos or edit a document.
I tested the reader with the new LG G Pad and with Google's Nexus 7 tablet. It worked flawlessly wit the G Pad, but the Nexus 7 does not come with OTG (On-The-Go), a common feature with many other Android devices. To use the Leef reader, I had to install a third-party app like OTG Disk Explorer Lite (free) or Nexus Media Importer ($3.99).
The Leef reader is available at Amazon.com for $9.95 plus shipping.
