Any review for InstallMonetizer ?

Did someone here worked with InstallMonetizer ? I need a review of them.
I tested them for the rates but I need to know about payment. They pay ? I am just worrying about my money...

They pay, but not always. You are safer if you are from a 1st world country. I know of 2 instances where affiliates lost large sums from them
and given nothing more than flimsy excuse about poor traffic quality but I myself got paid from them no problems for several years.

I never heard about not paying...I am getting payments more than 2 years already.

I just started with them like few days ago.

Their support sucks big time, they reply if they feel like doing it lol

and i noticed they shave a loot, i mean a looot

InstallMonetizer used to work very well in 2012 but in early 2013 they started to become very strict in everything (there were some new investors and ownership changed bit), and it has brought down their conversion and rates IMO. but their blog is informative and shows they keep themselves up to date with the ppi market. i suggest InstallMonetizer when user experience is important for you besides income from ppi offers
