I have been using UserTesting for months now and its really great. I get paid on time every time and the support channels are very helpful. You have to get through a test to get accepted but its super easy and not a hassle to do. I will admit not being eligible for a lot of the tests can be annoying sometimes but the ones i CAN do are easy and straightforward to do with no fuss. Pay is through PayPal and its always accurate and on time. and if i have any issues i can reach out to support for help. Highly recommend if you want some extra money here and there.
