A basic BD-ROM drive that does exactly what it advertises. Retailed boxed product that comes complete with SATA interface cable, 4x mounting screws, and a replacement standard-size tray front for use with PC cases that have 'flip-down' doors in front of the drives (the fitted translucent tray front is slightly larger than normal and can jam the doors on this kind of PC case). Also includes a wire tool for opening the drive when powered off, which you need to do to change the tray front, and full instructions.
The included PowerDVD software is version 7, which is not the latest version, but works just fine.
I recommend purchasers install the latest firmware for this drive after fitting (available from the Sony website) in order to avoid compatibility problems with newer Blu-ray discs.
