I've never bought a 12-pack of SATA cables before, but it was worth it this time. Not only do I have backups (before I will need them), but they work as intended. The plugs move in and out without problems and stay where they are installed. They are a little difficult to pull out (i.e., when you need to do maintenance, etc.), but it wouldn't stop me from buying these again. They are definitely well priced.See full review
