I joined smiley recently, where they will send you products from various companies to try out and even share with friends at times. Then all you have to do is share your feedback on the tested product with smiley, by logging in to your smiley account and sharing it. You can also earn smileys, (smiliey points), by sharing your feedback with others on Facebook and Twitter. You can check them out here:
Smile.ly—Be Heard. Be Happy.
