Online surveys and shit?

Has anyone actually eva made any money off of online surveys? Right now, me and my girl have been experimenting with alot of these sites.

Im not sure how it will turn out, but if any of you out there got any feedbacc or experience with this kinda shit...PLEASE RESPOND and let me know tha ins and outs...feel me?
