Rewarded Installs for Mobile Apps - need your opinion!

Hi guys!

I’m doing research for an article on incentive traffic for Android apps. Will appreciate you anwers:

Has anyone tried buying rewarded installs from platfroms like AppBooster or Tapjoy?
Was it positive/negative experience?

Would you rather use self-serve platform for buying incentive traffic, or work with media buying team who would take care of setting up campaign?



I have tried to buy rewarded installs at cheapest service available for all app reviews. I was very satisfied with my result, honesltly. God bless you!
