You will complete 90% of a survey and just to be told "sorry, but your responses dont qualify for this...", after you've already spent 10-15 minutes answering questions! THEN, even if you do qualify for some, and build up a enough points to check out a reward, it will give you an error EVERY SINGLE TIME you try and check out. Not worth the time and frustration. There are much better and more reputable sights out there to join (such as IPSOS)
