Thin, low profile and great quality.
Yes they're a bit dearer than other SATA 6G cables and these are shorter as well but providing you're not running your HDDs up high somewhere in a full tower case then most will be just fine. They're really nice cables, high quality and makes cable organisation a breeze. I had thick cables before that would cause my side panel to bugle on the 650D... Not any more.Pic: http://i.imgur.com/CLQBvuL.jpgYes I need to get another :p
