A few general remarks about many negative reviews for Blu-Ray playback. Before a Blu Ray drive you Werkt At length itself, of course, should be checked whether their own computer at all meets the hardware requirements for playback of Blu Ray. In some older PC or notebook that is not automatic. Such checking tools are in the I-Net to find. The second requirement is the appropriate software for Blu-Ray (z. Ex. Win DVD Pro 11). That this drive no corresponding software is added is indeed clear from the item description.
Anyway, I'm absolutely satisfied with the quality and of course the very reasonable price (for my first external Blu-ray drive, I had to pay more than 100 euros).
So a strong buy recommendation and 5 star.
