I just did a grocery survey worth 576 points that took me almost 2 hours of work (the time length on their surveys list page said 50min). I TOOK NO BREAKS!! I finally finished it successfully, got to the end, and the redirect window popped up with "Session expired." So, of course, there will be no payment for this one!!! SCAM!!! This isn't the first time this has happened to me (but it WILL be the last!) nor the first time it's happened to other members. To be fair, I've earned a decent amount of petty cash from them, and always got paid eventually. I may try to stay with them a little longer but will only do shorter surveys for smaller point values. The major ripoff risk otherwise is just not worth it. PS - Customer service won't help in these cases, just offer their condolences for your bad experience, if they even get back to you at all.
