This is the best platform for testing and providing feedback for companies in return for compensation. I like it and take it very seriously and believe the rating system they use is very logical. BUT, there are 2 things I dislike. First, most clients dont even give you a rating or feedback (which is ironic) they only give you a rating if its really bad otherwise you can do 70 tests which remain unrated and 1 bad test rated as 3 stars and thus ur rating is 3 stars. The other thing is you are likely to encounter some tests that are simply bugged where a button just doesnt work in the usertesting interface and there is no way to move forward or back, and that way you just lose the test. This is my experience truthfuly I will continue using this platform and giving it my all.
