I love that they have so many options of ads to choose from, as well it is very easy for me when managing my account with them due too its being an online platform.
No downsides yet but i am sure there will be one day because this business has been around since 2012! Great software if you are looking into advertising your new website or blog through responsiveads services, great prices compared to other similar platforms out in market nowdays.
Definitely considering using their service again…
