All 3 PPD networks that I've been with has crazy long surveys that treat our users like shit. I tried doing a few on my own and holy shit, I would never actually do those surveys to download anything. It's not even the fact that they are long, but here are some more things: - Uncertain on how long survey is. Could be 3 or 30 more minutes. - Don't know if it will even callback and allow person to download after completion. - I can't choose which surveys I want to offer. Have you guys ever tried a survey and got one done in under 30 minutes? If so, where? Which offer?
