Has anyone bought any of these Silver Flex cables?

Silver-Flex Stereo Audio Cable with Silver Plated RCA Connectors with Black and Red Anodized Aluminum Shells and White Belden 1505F Cable, Lengths from 1-75 Feet

They look pretty good for the price.


And these look similar to Bluejeans-

Belden-Canare Studio Grade Stereo Audio Cable, 1.5 to 75 feet long, Belden 1505F black cable with Crimped on (cold welded) Canare RCA connectors and Techflex outer jacket
