...as the cable that you will get - at least the one I received - had right angle connectors at both ends... while the description "right angle one end" this is supported by the picture. You usually want a straight end to connect to the motherboard and a right angle to connect to your HDD, DVD drive etc...
Otherwise the cable quality is not outstanding but good enough to do the job. For the price it is a very good deal, your would pay around £5 at Novatech for the same quality. Startech delivered very quickly, if they would have delivered the product ordered it would have been 5 stars.
