I am very disappointed with the purchase of this cable. During construction, I installed over 2,000 feet of this cable in my home. After the final installation, the speed was very slow. I have a download speed of 200 on my router and switch. In each of the endpoints the speed is only 50-60. I hired a professional network/IT company who ruled out hardware issues. They found that the very low speed and high impedance was due to the quality of the cable - the wire is very thin and the copper shows through. The only solution is to pull the wire out of the walls or rewire a good quality Cat 6 throughout the house. This rework will cost me a lot of money and time. I am very disappointed with the result and was ultimately doomed when I ran this cable.
