Your experience with using tapjoy for mobile ad revenue?

I have tried and tried but i just cant seem to get ads to show on my mobile app as is.

So i am thinking of using 3rd party plugins such as tapjoy to monetize my free app.

Anyone has any experience with it?

  1. Is it free to use? (Nothing is free but do i need to pay upfront cost or do they deduct from my ad revenue?)
  2. Is it easy to set up with blueprints projects or is it quite buggy?
  3. Obviously i will read the EULA myself but is it a standard agreement or are there any odd clauses hidden in there?

Thanks for your input.
