Love them. After switching to Gigabit service through my ISP, I became obsessed with maximizing download/upload speeds to experience true Gigabit service. I have compared them to Vandesail Category 7 flat cables and Category 6 Mediabridge cables (although their specs say they are also Category 6a) and Category 8 cables from an unknown brand. They always gave me the best/fastest of everything and I never had any trouble connecting with them. I tested the output directly from the modem, and each time I tested each of them coming out of the switch under the same conditions. This would be my recommendation, especially for the price.
