"I have purchased thousands of dollars worth of drives and products from OWC, but the last purchase has changed my opinion. I purchased an external HD, a 1 TB internal and a USB enclosure for the old HD (from 17" Macbook pro) so it could be repurposed as a portable external drive. I talked with the sales person to be sure the new drive would fit and the old drive would fit in the enclosure. He told me the enclosure would fit all 2.5" drives. I installed the new drive, and noticed it was thinner than the existing drive. When I tried to put the old drive in the new external enclosure- it wouldn't fit, the drive was too thick. I called for an RMA, but was called out of state before I received it. By the time I returned the RMA had expired. A call to OWC revealed they don't make an enclosure to fit my drive, and they wouldn't refund my money even though it was their mistake. I run an ad agency, and I always advise my clients that it's bad business strategy to save a few bucks but lose a loyal customer. OWC has done just that."
