Kudzoo is far from perfect, but avoid taking the cons people list to heart.
There are no pop up ads, annoying banners, or suspicious links. Because Kudzoo relies on companies for restocks, they cannot fully control how quickly or frequently new rewards are put up. Consequently, there is a high demand for restocks, and they will sell out quickly. As users profiting at no cost other than two/three minutes a day, all I can hope for is that students dont feel entitled to receive rewards. Be patient, check for restocks daily, and youll eventually get the pay off.
