I recently received an email to try ValueImpression and have decided to test them for a month. Their Net-0 payout term is what caught my eye.
For now, ValueImpression has approved my account but talking with the account manager on Skype has been the worst experience so far. He keeps me hanging half the time and decides to switch the conversation to email while leaving the questions unanswered on Skype.
And strangely I have not received an invitation to Ad Manager. Most networks similar to ValueImpression send an Ad Manager invitation email to enable Google AdX demand.
If any of you are using ValueImpression, please share your experience specifically payment and support time.
