Recruiters - Do you actually use ZipRecruiter?

I was just in my car at lunch and within 10 minutes I heard two commercials for ZipRecruiter claiming that 3 in 4 employers got their last employee from ZipRecruiter. And um, I call BS on that because I don't know any candidates actually using it. I know plenty that have tried it and found it to be a wasteland of scams and sales people but rarely any actual jobs. I'm wondering if the same is true from your side of things.
