I like it because of its simplicity, which is very important when you're using software as your main tool! I also appreciate how easy they make things with their support team (even though sometimes we need more than just answers - but not many problems really). There's nothing much about this product yet there has been no major downsides so far either; maybe if i had some other suggestions or improvements then feel free to contact me ;) Good thing was that my agency made everything from scratch without any help at least once until now :) So even small businesses could do something alike too. Using DJaX adserver allows us manage our own campaigns while having full control over bids/costs etc., making sure every client gets what he wants most out off his budget spent. I like how easy it is to use as well as its fast loading times. It has helped our agency with creating a new revenue stream, which is great! I would suggest more ad networks be added to help expand our client base. Currently we have only been using this service for about a month and have not had any problems. We are now able to place ads on websites that were previously difficult to get approved for due to their high cost.
