I purchased a very similar model (P25) from Norazza and wasted a tremendous amount of time (and blank DVDs). The copied disks would work on some DVD players and not others. Like most users, I assumed it was my fault. But after copying different non-commercial DVDs and testing them, it turned out that the Norazza copier did not produce disks that were compatible with some players.Unfortunately, I figured out the problem after the one-year warranty had expired. It took two emails to Norazza to get a response and there was no remedy. I threw the device in the trash this evening.Mine was an old model, and newer models are probably fine. But, if you purchase this duplicator I would immediately copy different CDs and DVDs and test them on different players. (Obviously, this device can't copy protected DVDs from your local video store-- I'm referring to movies made at home).I have no desire to discredit this company, but I think other customers should know about my experience.
