You may think you'll buy a 1000ft cord spool when you have multiple lengths of cord on that spool and you never know how long your next length will be and if you can use it because it is jammed or damaged. This is by far the worst Cat6 cable I have ever bought. I had already used 200ft of cable when I realized how bad and damaged the cable underneath was and it was probably too late to return it. But the next time I buy a cable, I will study the information better.
