I use this cable for an external 2.5-inch hard drive to a TV from LG. At first I used a USB extension cable, but had the problem with that power supply via USB was repeatedly interrupted. With this cable it works, however excellent. With the help of this cable do I need no more extension, but can connect the hard disk directly and through a decent length. In addition, the connectors are gold-plated and the cable is very broad. This can point to a very good quality.
Summary: + Works with an external 2.5-inch hard drive (no external power supply) + Quality is very good
