They are new to me. I did a search and wasn’t able to turn up much online, other than this – Someone thinks they are more of a “survey router,” not the same as answering Q’s directly for a survey panel. So I think I personally wouldn’t sign up, but as always I recommend that you do you your own research in addition to the research I’ve done.
It’s easy to earn cash for surveys. How much you get paid completely depends on how many paid surveys you attempt and complete. Each online survey has a different payout, with some offering as much as $50. Most will pay less, but also take less time. Expect to earn about 40 to 200 SB points per survey (100 SB = $1), with occasional opportunities with much higher earning potential.
