Contrary to what they tell you in promotional material and your sample video, you will NOT be reviewing sites/products/etc. They say you will be paid for making excellent video reviews and this is not true.
ALL of the "tests" are product testing surveys, identical to Respondent.io and are primarily programming based. I have yet to see one video review job. They are all software product testing surveys.
If you want to do software product testing, visit Respondent.io, they pay more than UserTesting and dont require a BS sample submission video nor are you given "ratings" by "moderators".
