Not a site that will "make you rich", but they don't promise that! A good place for some spare change and some great shopping tips and coupons.
The surveys have some very interesting topics. Occasionally there are some that don't work, but it is usually on the end of the Marketing company, not QR.
Fun games on their connected Facebook page - daily games and some occasional "bonus" games. The community is also very helpful when someone posts a topic or a question.
Not the fanciest graphics, but a simple, honest site. I was very suspect at first, worried about viruses or a scam, but have yet to have any adverse problems (I run my virus check regularly, and I get more from my "friends" emails!)
Great response from the support folks, very responsive to ideas. They continually try to add new sources for revenue... and fun. Check them out!
