I did not know this could happen but a batch of bad blank CDs ruined TWO CD/DVD drives before I realized what was going on. Thanks Geek Squad for the heads up about that one! So the CD/DVD drive on my laptop no longer works and neither does the $60 external one I bought at Staples. I needed a drive. I found this one and decided to risk buying it because the price was right and so were the features. I have used it several times to burn music CDs from iTunes and it has worked perfectly each time. I honestly have not tried to burn a DVD so I cannot attest to that. But for the price, this is worth it. It saved my computing experience because I can now, once again, read and write CDs.
