Summary: I was pleasantly surprised with this item! I had been searching for a portable dvd drive for my macbook air and didn't know which one to go with. I borrowed my father's a few times before (he has one by Transcend in black). The one I received is thinner than the one my father has which I love because it's not as bulky! It is extremely lightweight and looks lovely with my macbook air :) Many people mentioned the drive only works if you plug in both USB cables.
Summary: Product comes with two USB connectors, but my computer only has one. The purpose of the second connector is to provide additional power to the unit. With one USB connected it will read and write files, but it will not play a DVD movie.
Excerpt: Unable to select no stars so had to put 1. Purchased this to use with Surface Pro 3 but will be returning it. Requires 2 USB ports to use (not mentioned anywhere online or on box). Will not work with Surface Pro 3 which only has 1 USB port.
