Exceeded my expectations in every way.

Great quality solid copper cables. None of the local stores, such as Walmart or Autozone had Any real copper cables at all. All offerings were CCA dual-conductor cables that are essentially 95% aluminum. 2/3rd of available options had Packaging that didn't openly disclose this fact. It took time researching each "high-performance", or "professional grade" audio cables they had in stock. Perhaps, there's no regulations that require manufacturers to to make any reference clarifying that the product isn't pure copper. It was surprisingly misleading. Amazon Basic branded cables are as good as the best cables you cables you can buy elsewhere online. 14 Gauge us about as thick as you could reasonably use at home without it becoming a major annoying mess. Great price as well. Made in Vietnam - is just the icing on the cake. Ordered the "used" option. Cables were brand new, the coil was slightly banged up in shipping and dusty, thus the 15% discount
