I am preparing to get some user feedback on my site, and have the following options:
https://www.usertesting.com/
https://userbob.com/
https://www.ubdi.com/individuals/how-it-works
https://www.prolific.co/<p>Has anyone used any of the above services? If so, I appreciate your feedback.<p>Alternatively, I could buy some FB or Google ads to my landing page and try and setup a hangouts call with every person that enters their email address. Any feedback on this?
