I once bought four toolless 2.5" USB drive cases from this vendor whose name starts with "O." If I could, I would rate them -1 star Just the other day, I thought that three external hard drives failed. It turns out that the drive cases all failed. When I put the raw drives into a "drive dock," and tested for bad sectors with Windows chkdsk, they were all 100% error-free. All these cases were made by "O." The fourth case failed a few months ago. Previously I had a drive bay card reader by this same vendor fail. Sure they are low-cost. But it's just not worth the hassle, and then you have to spend more money to buy a quality product.
