The ease of use, flexibility in targeting options as well their customer service has been great! I have had no issues using canned banners for our client portfolio at this time so far they've done an excellent job helping us figure out ways we could improve performance & optimize campaigns/funnels etc.. They were able solve any concerns which gave me peace-of mind about implementation going forward (which was very important). If you're looking into adding some type of product line be sure it's something your team will enjoy working together towards building - if not expect difficulties along way. We implemented them initially because 1) Their pricing structure made sense compared other similar products 2.) Our website traffic data supported what seemed like good fit 3.). It helped take load off my plate since i wasn't doing heavy lifting managing banner ads myself 4.)They offer more than one option for creating different types of content 5.)Their tools are easy enough.
