I have been working with Monsters since February of this year, and I have only positive impressions. The support is up to the mark, I've worked with several managers, any questions are solved promptly. If there is a problem with processing of the leads on the side of an advertiser - they always take the side of the webmaster, ready to compensate the expences. Payments are held without delays, it is convenient to withdraw to the card without a fee or to the account of IE, they add plus 6% to the payments. There are many interesting offers, including bourgeois, they are trying to be the first to bring new items on the market (I started working with them - with an offer that was nowhere else but this affiliate program). The interface is user-friendly, you can quickly pump out any offer tuned to your api. Overall, I recommend it.)
