I have cleaned out two old broken laptop and installed the hard disk in the case of two. The installation was very easy, because everything can be done without tools. Only one pushes the housing, then comes in the hard disk and then you push the housing again. Direct the plates each connected to a USB port (Macbook Pro, Macbook Air, Netbook and Windows PC Stand) could be connected and used. What little the extremely bright blue LED but bothers me that always lights up ... but that's for this class price more than bearable.
