The connector that came with my HDTV stuck out enough from the wall that I couldn't get the TV mounted flush.  This worked great.  Besides being flat, the plug rotates - very nice feature.  The price was pretty good too (even tho S&H more than doubled it).  Just to note: this is not a typical extension cord, it has one end that is made to be used with the special power connectors used on many computers, printers and TVs.
