Summary: Only after I purchased it, I learned it does not include a software for blu-ray playback. In the description, it talks about 3d support, 2d to 3d conversion and 'Magic Cinema' 1080p upscaling all indications of a software which can play blu-ray disks. So its promotion text is in a sense misleading. I haven't tried the burning/writing features yet so can't comment on that now.
Pros: Light and portable. Burns and writes to blu-ray and dvd disks.
Cons: It does not come with a blu-ray player software.
Excerpt: The drive looks nice and comes with a stand, but the usb port on the drive itself is hard to plug into sometimes. The drive views and burns disk with ease. But beware that you have the codecs install for dvd and Blu-ray if you want to watch movies. Also, not all laptop displays are rated for Blu-ray even if stated as HD Display.
Excerpt: On deadline for an award submission I discovered that my documentary had to be delivered on Blu-ray. I didn't have time to research or shop. I feel very fortunate to have had a perfect experience with this burner. Other than the fact that my iMac did not immediately detect the device (and after a Final Cut reload, iMac restart and a cold boot failed) I used Disk Utility where the drive appeared with a drop-and-drag option.
Summary: Bought this to watch Blu-ray movies on my older iMac (less than the 'recommended' CPU speed and video card) with 3rd party software as required. It works on the main USB connection with no need for the extra power connection!
