Love using User Testing, it’s a chance to give feedback, make a difference and earn some money along the way. The tests are short, and easy and you can do them in your own time. If you are lucky you can be invited to high paying video call tests on a 1 to 1 scenario to give feedback and your opinion towards developing websites and apps - your opinion is as a user and not technical at all. I would highly recommend giving them a try. I didn’t get a lot of tests in the first year - but two years in I get quite a few in a week - love it!
