SurveyRewardz is very easy to use and is a survey site with a good amount of opportunities.
You can only earn by taking surveys, but there are usually several daily opportunities.
If you do not qualify for a survey, the panel will scan to find another survey that is available for you instead.
Sometimes it can take a bit of time for it to find surveys you will be able to complete, but it is a great function that it keeps scanning, as this makes it easy to find survey opportunities.
You earn points when you take surveys on SurveyRewardz, and these can be exchanged into rewards.
