Hmm... Are you willing to pay some 3 orders of magnitude more for 4 non-crap twsited pairs made of pure* 99,99999999999678774% copper, plus only the finest nylon money can buy from a factory in China, the finest gold plating in the world and a RJ-45 connector, crimped to perfection by Japanese crimping masters, with an unbreakable tab. Plus, an engineer** will personally test the cable and hand-paint arrows on it so that you know in which direction the data flows better, allowing you to experience more of your audiovisual library than you thought possible. We'll also throw in free shipping if you live in the US. If you're really lucky, your cable works just as well in either direction, so it's like playing the lottery, only better! ***
* Purity may vary between 98,0% and 100%
** Is not guaranteed to be an electrotechnical engineer. May be some schmo who draws nice arrows, under supervision from a civil engineer or a robot who has been taught to draw arrows and is supervised by the janitor who was taught to press a red button in the event of a breach of Asimov's laws of robotics.
*** Purchasing this cable is nothing like playing the lottery, playing the lottery gives you an tiny chance of something good coming out of your investment.
