Using this microSD USB reader is a breeze. First, take your microSD card and slide it into the inside of the USB connector. Then, plug the reader into a USB port on your computer. Right away, the contents of the card will show up on your screen. It's a plug - and - play device, so you don't have to worry about installing any drivers. Note that the microSD card is sold separately, so make sure you have one. The indicator LED on the reader will light up if there's a microSD card inside, which is a nice way to know it's working. To keep it in good shape, handle it gently. The removable cap can protect the connector when not in use. And you can use the keychain lanyard to carry it around easily. Enjoy using your reader to access data from your microSD card!
