Got the Samsung USB Adapter recently. It's a very handy piece of kit for using regulat USB thumb drives with the Note 3. Should you get one don't worry that the box says Samsung Galaxy SII it still works withe the Note 3. I'm using it now to transfer 14GB of old time radio files from my Samsung 64GB MicroSD card to a Sandisk 64GB microSD card with a thumb drive adapter.
