I've been participating with e-rewards for several years...
I've been completing surveys for e-Rewards for several years now, and enjoy redeeming points for gift cards at a few retailers that I frequent. I like the variety of survey topics and that I can complete surveys at my own pace, meaning that if I want to participate, I can, and if I don't have time, there is no penalty for taking days/weeks off. Now, there are some things I do find frustrating, including that you can spend considerable time completing a survey, receive a "thank you for your participation" message, and then be told you are disqualified. Some surveys seem way too long for the amount of points that you receive. Customer service is inconsistent in how they help you resolve issues; some reps are helpful, and others seem not inclined to help at all. I feel frustrated when I don't receive a full explanation for survey issues. So I would recommend moderating your expectations when participating with e-rewards and go in with the expectation that sometimes the process will go smoothly and other times it won't.
