Product testing is much like taking surveys; you are selling your opinions. The main difference is, with product testing, you get products or services to try out for free! I am only signed up with one of these companies myself, but I have received air freshener, facial cleanser, shampoo, and toothpaste to try out! All full sized containers too!
