Scott, most of those time estimates are grossly exaggerated. But regardless of that, if you get a survey you don't want to complete (for whatever reason), just answer the first few questions in such a way as to get automatically disqualified. Usually, saying that you work for a market research company will do the trick. That way, you spend only a minute on the survey and still earn the "not qualified" amount, which is usually $0.50 or $1.00.

This way you can still earn SOMETHING even on surveys you don't feel are worth completing.

For my part, I've been getting about 1-2 eRewards surveys and "quick studies" per day recently, averaging to something like 20 offers per month. I have rarely had an issue where it took me too long to get disqualified - almost always if I'm spending more than a few minutes on the survey, I am fully qualified and receive the credit. I, too, have sometimes had problems with surveys not crediting, but a polite email to customer service almost always results in a fix within a few business days.

It may not be the best survey company out there, but it's good enough for what it does, IMHO... at least for me. Clearly, some others have not been having such good experiences.
