Horrible. It takes many hours to make 1 dollar, let alone 30 dollars, which is what you need to cash out. It takes about a year to make 30 dollars unless you’re at it every day, then it should take you only10 months. Don’t waste your time. There are too many survey sites that are much better. Inbox lets you answer a whole lot of questions which they keep, before they decide you are not the perfect fit. Makes me think they have the answers they really needed from you. They should investigated and shut down.
The only reason Springboard didn’t rank higher on our list is because some users have reported a fairly limited supply of available surveys, making it difficult to reach the $50 minimum cashout threshold. However, the availability of surveys depends on your demographics — so my recommendation is to join, making sure your profile is 100% complete, and then see if enough opportunities come your way to make it worth your while.
