Aluminum External USB DVD+RW,-RW Super Drive for Apple--MacBook Air, Pro, iMac, Mini I purchased this item from Seatech through Amazon. I was buying it to replace the dvd drive on my iMac, which stopped functioning. The drive on the iMac was still covered for repair, but I found through research, that many people had problems with the built-in drive's vertical set-up, so I chose to replace it. It arrived much more quickly than anticipated. I had some problems at the start (my own fault, as I wasn't pressing my dvd down on the spindle hard enough. At first I was kind of annoyed, blaming the product, but the gentleman I made contact with at Seatech was very nice and patient, finally offering to send me a second dvd drive to try. This again arrived in two days. It took some time for me to figure out what I was doing wrong and again the gentleman at Seatech was very patient. I am totally pleased with the drive now.I have used it to install programs and I have used it, in conjunction with my Mac's idvd program, to set-up and burn a dvd. I am, at this time , thoroughly pleased with this drive.It is simple to use, inexpensive, remarkably thin, and very easy to set-up. Moreover the person I've dealt with at Seatech was friendly and accomodating in the extreme. I highly recommend this drive for use in conjunction with the newer iMacs that don't have a built-in dvd drive and with older iMacs, as an inexpensive way to replace a malfunctioning dvd drive.
