Effortless configuration just plug and play. The best way to transfer files quickly between Computers and Smartphones would definitly recommend it. It is fast and versatile and for the price of $6.99 it is a steal! You can either inser a micro SD Card or a Regular SD Card into this device which is great because if you don't have an adapter at hand you can use it without it, which you can't do with your stock SD Card Slot on your Computer.
