UserTesting does pay what it promises, however it can take a lot of time to get through all the "screener" tests before finally being eligible for the actual paid test. I am generally eligible for tests 1-3 times per week. If the site glitches and you are unable to complete the test or if the test does not upload to the customer correctly, they will not pay. It's a good source of a little extra cash if you have a lot of extra time on your hands.
