Unusually, this cable is manufactured in a flat style rather than the round style most often encountered. It works well and delivers the speed one expects when using devices with eSATA. If there is a criticism, it is a minor one, and it is that it is difficult to ascertain the top side of the plug from the bottom. With familiarity, it is possible but there is no obvious marking as there often is with USB connectors, for example. That can easily be resolved with a dab of Tippex or coloured nail varnish if necessary.
Works well and thus recommended.
