I have been checking out several sites over the past few weeks and have found 4 (out of 9) which seem to provide a little cash (I have not yet cashed out of any of them, so only carry a balance of points or dollars). I can cash out/redeem with 3 of the 4 sites. these are the 4:
SurveysOnTheGo -- i signed up about 2 weeks ago and have taken a lot of surveys -- most which I screened out. I currently have $14.25 in my account with another $2 pending. I allow location access but do not allow data access nor did I install the browser extension.
Branded Surveys -- I signed up a week ago and currently have 828 points which is $8.28. I take 5-6 surveys a day and screen out of most. But there are always surveys
SurveySavvy -- I signed up a week ago and currently have $12 from surveys and am expecting an additional $10 per month from the installation of SavvyConnect on my Tablet and Cell. This is the only site I downloaded or allowed access to my data other than location. The reason I chose this site over others is that they seem to pay the most ($5 per month per device -- up to 3), and because of the feedback I received from members of this Forum after I asked about the site in a topic.
Swagbucks -- after 2 weeks, I have 433 SBs from surveys. I won't do the other games and stuff they have to earn more points.
Hope this helps
