I've been paid out roughly 20 times from prizes that range from 5$-25$ gift cards. I usually only get Amazon, and they pay out within 24 hours each time.
Never had any issues with them. Just put effort into your posts and you'll never be wronged by them. Cashed out around 300$ so far in my 9 months of using them.
They also run free samples, so far I've been accepted into a free battery pack and it's pretty good quality too.
