Has anyone used Adroll (Facebook retargeting)with any success?

[Gordian]

Hello!  I am wondering if anyone out there has had a good experience with Adroll.  I set up a campaign a couple months ago, but have yet to see any return on my investment.  I'm now considering stopping this service because it seems to not be living up to its hype.

What has your experience in using this service?

I tried to sign up with them, but they scoffed at me when I showed them my traffic report. "We don't provide support for clients your size. You can use our service but you'll need more traffic to see any results."

It was a total turn off.
