a lot. I finally had time to use this wire and attach the first connector and when I rolled it out I found I was missing a lot of wire. Like 75 feet. I need this referral, but it's mostly mailing because it's been a lot lately and if I waited another week I wouldn't have a 30 day return window. I'm not saying that the wire is bad, just lately I'm really worried about inaccurate commands. Please make sure you get your 100 feet.
